Also, I should not that this problem does not occur on my testing VM, only on our production server (so I'm not quite sure what the problem is). webmail-error.log: [Wed Jan 20 23:38:17 2010] [emerg] mod_fcgid: server is restarted, 32760 must exit wiki-error.log [Sat Jan 23 15:03:25 2010] [emerg] mod_fcgid: server is restarted, 22502 must exit [Sat Jan 23 15:03:25 2010] [emerg] (22)Invalid argument: mod_fcgid: can't get lock, pid: 22502 [Sat Jan 23 15:03:25 2010] [emerg] mod_fcgid: server is restarted, 16264 must exit [Sat Jan 23 15:03:25 2010] [emerg] (22)Invalid argument: mod_fcgid: can't get lock, pid: 16264 [Sat Jan 23 15:03:25 2010] [emerg] mod_fcgid: server is restarted, 22501 must exit [Sat Jan 23 15:03:25 2010] [emerg] (22)Invalid argument: mod_fcgid: can't get lock, pid: 22501 error.log [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: process /var/lib/mediawiki/index.php(22557) exit(shutting down), terminated by calling exit(), return code: 0 [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: process /var/lib/mediawiki/index.php(22561) exit(shutting down), terminated by calling exit(), return code: 0 [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: process /var/lib/mediawiki/index.php(22562) exit(shutting down), terminated by calling exit(), return code: 0 [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: process /var/lib/roundcube/index.php(2380) exit(shutting down), terminated by calling exit(), return code: 0 [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: process /var/lib/roundcube/index.php(5653) exit(shutting down), terminated by calling exit(), return code: 0 [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: process /var/lib/roundcube/index.php(6212) exit(shutting down), terminated by calling exit(), return code: 0 [Sat Jan 23 15:03:27 2010] [notice] mod_webauth: initialized (3.6.0) (Built by buildd@excelsior on 2008-05-02 22:03:49 UTC) [Sat Jan 23 15:03:27 2010] [notice] Apache/2.2.9 (Debian) mod_ssl/2.2.9 OpenSSL/0.9.8g WebAuth/3.6.0 configured -- resuming normal operations [Sat Jan 23 15:03:27 2010] [notice] mod_fcgid: call /var/lib/mediawiki/index.php with wrapper /var/lib/mediawiki/fcgi-wrapper/php-cgi-suexec [Sat Jan 23 15:03:28 2010] [notice] mod_fcgid: call /var/lib/mediawiki/index.php with wrapper /var/lib/mediawiki/fcgi-wrapper/php-cgi-suexec [Sat Jan 23 15:03:28 2010] [notice] mod_fcgid: call /var/lib/mediawiki/index.php with wrapper /var/lib/mediawiki/fcgi-wrapper/php-cgi-suexec It looks like the emergency messages about being unable to get a lock on these processes is what's causing Apache to hang until I forcefully kill them.

Killing off all FCGI processes and the www-data Apache processes seems to let it continue working, but this shouldn't be happening. >> >> Here's the setup for one of my vhosts (one other is set up similarly, and suexec is otherwise not used at all - mod_suexec is not enabled): >> >> dr-xr-xr-x 2 www-webmail www-webmail 4096 2010-01-20 21:57 /var/lib/roundcube/fcgi-wrapper >> >> -r-xr-xr-x 1 www-webmail www-webmail 95 2010-01-20 21:57 php-cgi >> #!/bin/sh >> export PHP_FCGI_CHILDREN=0 >> export PHP_FCGI_MAX_REQUESTS=4000 >> exec /usr/bin/php5-cgi >> >> -rwxr-xr-x 1 root root 71 2010-01-20 21:34 php-cgi-suexec >> #!/bin/sh >> exec /usr/lib/apache2/suexec www-webmail www-webmail php-cgi >> >> And here is the relevant line in the vhost configuration: >> >> FCGIWrapper "/var/lib/roundcube/fcgi-wrapper/php-cgi-suexec" .php >> >> Any thoughts or tips? >> >> -- >> Jeremy R. >> Owner, NovaWave Solutions >> http://www.novawave.net/ >> >> >> --------------------------------------------------------------------- >> The official User-To-User support forum of the Apache HTTP Server Project. >> See <URL:http://httpd.apache.org/userslist.html> for more info. >> To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx >> " from the digest: users-digest-unsubscribe@xxxxxxxxxxxxxxxx >> For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx >> > > Jeremy, > > Check your error logs. > > Thanks, > Daniel > > --------------------------------------------------------------------- > The official User-To-User support forum of the Apache HTTP Server Project. > See <URL:http://httpd.apache.org/userslist.html> for more info. > To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx > " from the digest: users-digest-unsubscribe@xxxxxxxxxxxxxxxx > For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx > -- Jeremy R.
