Description Martin Schl 2002-08-03 13:59:16 UTC
If my apache2 server has been running for 'some' time (perhaps an hour) and i
try to stop it with the service monitor, it seems to hang and maybe a minute
after that, my machine reboots.
I can stop apache2 without problems within a few minutes after startup.

Excerpt from my error.log:
[Sat Aug 03 12:31:14 2002] [notice] Parent: Created child process 1660
[Sat Aug 03 12:31:14 2002] [notice] Child 1660: Child process is running

process is ending.

[Sat Aug 03 13:27:23 2002] [notice] Child 1660: All worker threads have exited.
[Sat Aug 03 13:27:23 2002] [notice] Child 1660: Child process is exiting
[Sat Aug 03 13:33:18 2002] [warn] pid file C:/Programme/Apache
Group/Apache2/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run?

The above mentioned "unclean shutdown" was of course a reboot.
Interesting detail: 1878034896 seems to be a magic number, because it's always
"1878034896 threads" before my machine reboots.

My machines system protocol contained this (german system):
Der Computer ist nach einem schwerwiegenden Fehler neu gestartet. Der Fehlercode
war: 0x00000076 (0x00000000, 0x8194fc20, 0x00000001, 0x00000000).

Apache used to work on my machine without problems and i didn't touch the
config. I guess, it must have been due to installation/deinstallation of some
other program or windows patch.
The last patch installed a day before trouble started was Windows Hotfix Q318138.

Hope you can help.

  Are you using _any_ antivirus or firewall software?  Some, such as 
  ZoneAlarm, are already known to have bad interactions with the Apache
  tcp/ip stack.
Comment 2 Martin Schl 2002-08-04 11:07:20 UTC
Hm, i'm afraid that _might_ be the cause.
I updated my zonealarm a day before the trouble started.
Before i was using Zonealarm 2.6, which worked fine with Apache. But then i
updated to 3.125

Don't know what to do now though. Maybe i should reinstall ZA2.6.

Or is there a workaround to fix the problem?
