Hello, I have a problem where my Apache procs are dying almost exactly every ten minutes as you can from the messages and web logs below: Oct 25 10:34:44 kernel: pid 66337 (httpd), uid 80: exited on signal 4 Oct 25 10:35:33 kernel: pid 66357 (httpd), uid 80: exited on signal 4 Oct 25 10:45:11 kernel: pid 66395 (httpd), uid 80: exited on signal 4 Oct 25 10:55:21 kernel: pid 66340 (httpd), uid 80: exited on signal 4 Looking at the Apache logs, I find the following: [Thu Oct 25 10:25:01 2007] [notice] child pid 66379 exit signal Illegal instruction (4) [Thu Oct 25 10:34:44 2007] [notice] child pid 66337 exit signal Illegal instruction (4) [Thu Oct 25 10:35:33 2007] [notice] child pid 66357 exit signal Illegal instruction (4) [Thu Oct 25 10:45:11 2007] [notice] child pid 66395 exit signal Illegal instruction (4) I tried upping the logs all the way to debug today and it really wasn't very helpful: [Wed Oct 31 15:59:19 2007] [debug] prefork.c(991): AcceptMutex: flock (default: flock) [Wed Oct 31 16:05:39 2007] [notice] child pid 73668 exit signal Illegal instruction (4) [Wed Oct 31 16:12:01 2007] [info] server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers), spawning 8 children, there are 4 idle, and 17 total children [Wed Oct 31 16:15:04 2007] [notice] child pid 73779 exit signal Illegal instruction (4) [Wed Oct 31 16:15:28 2007] [notice] child pid 73717 exit signal Illegal instruction (4) [Wed Oct 31 16:18:37 2007] [notice] child pid 95939 exit signal Illegal instruction (4) I don't believe the 'busy' message is accurate. I think it's a result of the procs dying constantly as I just don't get that much traffic. I also have no idea what is causing the illegal instructions because none of the logs point out any specific detail to help me track it down. I'm running the following: FreeBSD 6.2-RELEASE-p8 FreeBSD 6.2-RELEASE-p8 #3: Thu Oct 25 20:04:14 CDT 2007 :/usr/obj/usr/src/sys/GENERIC i386 apache-2.2.6_2 Version 2.2 of Apache web server with prefork MPM. php5-5.2.4_1 PHP Scripting Language mysql-client-5.0.45_1 Multithreaded SQL database (client) mysql-server-5.0.45_1 Multithreaded SQL database (server) p5-DBD-mysql50-4.005 MySQL 5.0 driver for the Perl5 Database Interface (DBI) php5-mysql-5.2.4_1 The mysql shared extension for php php5-mysqli-5.2.4_1 The mysqli shared extension for php I'm using vhosts to host 4 different websites with different domains. The sad part is that these all show no errors in their logs even with them turned up to debug level. I've been looking at this off and on trying to solve it as time allowed since mid-September. I'm completely stumped and would appreciate any helpful suggestions where else I can look. Thank you!
