Bug 40800

As a work around I have changed the 403 errordocument:

ErrorDocument 403 /index.html

so the website visiters do not see this weird 403 problem (hopefully)

Are you using mod_cache? If yes please upgrade to the latest 2.2.x as  mod_cache
in 2.0.x is known to have several bugs.

mod_cache is not used:

http.conf: ===================================================

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs-2.0/> for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# The configuration directives are grouped into three basic sections:
#  1. Directives that control the operation of the Apache server process as a
#     whole (the 'global environment').
#  2. Directives that define the parameters of the 'main' or 'default' server,
#     which responds to requests that aren't handled by a virtual host.
#     These directives also provide default values for the settings
#     of all virtual hosts.
#  3. Settings for virtual hosts, which allow Web requests to be sent to
#     different IP addresses or hostnames and have them handled by the
#     same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/httpd/foo.log"
# with ServerRoot set to "/etc/httpd" will be interpreted by the
# server as "/etc/httpd/logs/httpd/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.0/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/httpd"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
#LockFile logs/accept.lock

#
# ScoreBoardFile: File used to store internal server process information.
# If unspecified (the default), the scoreboard will be stored in an
# anonymous shared memory segment, and will be unavailable to third-party
# applications.
# If specified, ensure that no two invocations of Apache share the same
# scoreboard file. The scoreboard file MUST BE STORED ON A LOCAL DISK.
#
<IfModule !perchild.c>
    #ScoreBoardFile logs/apache_runtime_status
</IfModule>


#
# PidFile: The file in which the server should record its process
# identification number when it starts.
#
PidFile /var/run/httpd.pid

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15

### Section 2: 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition.  These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.  
#
# User/Group: The name (or #number) of the user/group to run httpd as.
#  . On SCO (ODT 3) use "User nouser" and "Group nogroup".
#  . On HPUX you may not be able to use shared memory as nobody, and the
#    suggested workaround is to create a user www and use that user.
#  NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)
#  when the value of (unsigned)Group is above 60000; 
#  don't use Group #-1 on these systems!
#
User apache
Group apache

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
# ServerAdmin root@localhost

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work.  See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make 
# redirections work in a sensible way.
#
ServerName www.ipconsult.nl:80

#
# UseCanonicalName: Determines how Apache constructs self-referencing 
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client.  When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName Off

# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.

#
# Some examples:

#ErrorDocument 402 http://www.example.com/subscription_info.html

#
# Putting this all together, we can internationalize error responses.
#
# We use Alias to redirect any /error/HTTP_<error>.html.var response to
# our collection of by-error message multi-language collections.  We use 
# includes to substitute the appropriate text.
#
# You can modify the messages' appearance without changing any of the
# default HTTP_<error>.html.var files by adding the line:
#
#   Alias /error/include/ "/your/include/path/"
#
# which allows you to create your own set of files by starting with the
# /var/www/error/include/ files and copying them to /your/include/path/, 
# even on a per-VirtualHost basis.  The default include files will display
# your Apache version number and your ServerAdmin email address regardless
# of the setting of ServerSignature.

#
# Please see the documentation at

Additional info to this mistery:

- we have 2 identical compaq servers
- both mandriva, both identical
- 1 server is doing xpunlimited.nl
- 1 server is doing xpunlimited.com

the .nl server never has this 403 problem. The .com server quite randomly

I have started a bashscript
- while do each 20 seconds
     wget http://www.xpunlimited.com -o xpu.txt

Test the result in xpu.txt, being 200 OK or anything else
==> randomly not 200 OK but 403.........

weird.

Do an strace on one of the child processes when this is happening.

The most likely explanation is that the filesystem is simply telling apache that
the file does not exist.

> The most likely explanation is that the filesystem is simply telling apache

I can not aggree on this assumption
- the file exist
- the file exist using bash, ls command
- the file exist using SMB mounts
- the file always exist.

To reverse, why would apache think that the filesystem tells it that the file
does not exist, after several random hours or days.

if /var/www/html/xpunlimited/index.html does not exist according to apache, why
does a work around like deleting the content of /var/cache/https work.

I see no valid reason for the asumption that after a couple of hours the
filesystem tells apache that the file does not exist while other ways of asking
the file system about the file always result in the file index.html

As stated before:

> As a work around I have changed the 403 errordocument:
>
> ErrorDocument 403 /index.html

This work around works; apache is able to server the /index.html

So, the filesystem is not telling apache that /index.html does not exist. The
filesystem is telling apache that /index.html does exist.
In case the filesystem was telling apache that /index.html does not exist (which
is not the case), then apache should, as usual, generate the typical apache
error page about the error and that there was no errorpage for the encountered
error.
The fact that apache is able to server /index.html in case of a 403 error proves
that it is a weird error; 403 because /index.html does not exist and therefore
apache services /index.html..........

What is it that's getting written to /var/cache/httpd?  This is not referenced
anywhere in the configs you included.

And I'd still like to see the strace.

content of the folder /var/cache/httpd (not all of it)

The content seems to be, indeed a cache.
I think I could mount /var/cache on some fast medium like a ramdisk, and
increase the speed of apache. Right now, there is just 1 disk in the system with
ext3.

Some folders do have files. These files are copies of the html files in
/var/www/html. I discovered this, because, as stated before, apache kept on
serving old files despite the fact that files in /var/www/html were updated. I
discovered that this old content of old files was located in one of the sub
folders of /var/cache/httpd. Therefore I started the procedure
- stop apache
- delete all content of /var/cache/https
- start apache

This work around procedure is already a bit improved.
- delete all content of /var/cache/https
- restart graceful apache
I am thinking of scheduling this once 1 an hour.

It seems that apache accept the 'sudden' delete of all content in
/var/cache/httpd, without other problems.

Despite your denial you are using mod_cache. It may not be configured in
httpd.conf, but in one of the files included by httpd.conf, e.g.

# Bring in additional module-specific configurations
#
Include modules.d/*.conf

# include legacy conf.d during a transition period
Include conf.d/*.conf

So please refer to my comment here
https://issues.apache.org/bugzilla/show_bug.cgi?id=40800#c2.

If you intend to use mod_cache please upgrade to 2.2.x, otherwise turn it off.

Thx for your attention. You were indeed right; I overlooked the additional
includes. There it was; mod_disk_cache. Removed it and things are running smooth!
