Multiple Include directives in httpd.conf can cause a segfault on subsequent apachectl graceful or restart. Usually happens during the second or third graceful. Here is a snippet from my config: Include /export/kinetic/conf/apache/204.185.42.123/*.conf Include /export/kinetic/conf/apache/204.185.42.129/*.conf Include /export/kinetic/conf/apache/204.185.42.200/*.conf Include etc/apache2/Includes/*.conf
Could you please supply a backtrace as discussed here: http://httpd.apache.org/dev/debugging.html#crashes
I had to reinstall apache WITH_DEBUG. I then reproduced the bug and generated a core file. Here is the backtrace: #0 0x284da9fd in ?? () from /usr/lib/libpthread.so.1 #1 0x0000000a in ??

Furthermore line 32 of readwrite.c is the beginning of the function apr_file_read. There is no real code apart from "{" there. Which version of FreeBSD are you using? I saw discussions on the dev list about problems with FreeBSD and threads. As I have no experience with FreeBSD, some FreeBSD expert here to the rescue please.
Is /export a NFS mount?
FreeBSD 5.3-RELEASE-p20, prefork MPM. /export is local but shared via NFS. # httpd -V Server version: Apache/2.0.55 Server built: Jan 12 2006 13:17:46 Server's Module Magic Number: 20020903:11 Architecture: 32-bit Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_FLOCK_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D HTTPD_ROOT="/usr/local" -D SUEXEC_BIN="/usr/local/bin/suexec" -D DEFAULT_PIDLOG="/var/run/httpd.pid" -D DEFAULT_SCOREBOARD="/var/run/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/accept.lock" -D DEFAULT_ERRORLOG="/var/log/httpd-error.log" -D AP_TYPES_CONFIG_FILE="etc/apache2/mime.types" -D SERVER_CONFIG_FILE="etc/apache2/httpd.conf"
Is this still an issue in recent versions?
CC myself on FreeBSD related bugs
Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd. As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd. If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question. If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with. Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated.
