Problem with Apache22
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.

Do you have any processor-specific instructions in your make.conf? How did you install apache and other applications? Have you tried recompiling apache and php without any optimizations? Are you using PHP as mod_php? If so, you might want to try to switch to fastcgi to isolate if the problem is in apache or php. signature.asc Description: OpenPGP digital signature

RE: Problem with Apache22
Yes, it's using prefork. I made no changes from the default install. The results of ldd for each of these yielded "libpthread.so.2 => /lib/libpthread.so.2" in each case except for php and libmysqlclient.so.15, which both returned nothing. Running apache in debug, attached to the console resulted in output of "Bus Error" and nothing else. The web logs showed no errors at all. -Original Message- From: Philip M.

Annoying problem with apache22 / php5 - how to investigate?
Hi, We run 7-STABLE and apache22 with php5 serving pages from a webmail app (Horde). Randomly (as it seems at least), there is a 500 (Internal server error) and a blank page is presented to the user like [04/Jul/2009:15:19:37 +0200] "GET /services/portal/sidebar.php?httpclient=1 HTTP/1.1" 500 - There are no other messages in the logs, not even with LogLevel debug. The problem has survived several both OS and port upgrades and I really need to track this down now. Question: What OS tools would be the best to further analyze this? Someone with more exparience running this combo perhaps would know?

You're not looking at an Apache problem, but a PHP problem. 500 is the error code for a failed CGI script/program. Try executing the php from the command line. i.e. Go to where ever /services/portal/sidebar.php is and execute: ./sidebar.php httpclient=1 See what, if any, errors are thrown that way. PHP is notorious for not sending good errors into the logs or to STDERR. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

You can create an .htaccess file containing 'FAIL' and it will generate an 500 response. -- Glen Barber ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Likewise, I have E_ALL set in php.ini. So, I need to dig deeper inte the workings of Apache with the aid of the right tools. You're not looking at an Apache problem, but a PHP problem. 500 is the error code for a failed CGI script/program.

PHP is notorious for not sending good errors into the logs or to STDERR. You're right, I will see whatever logging I can squeeze out from the script handling. It's really annoying it's an intermittent problem...
