I don't know much about vlogger specifically, but it appears that it accepts log entries over stdin. In your vhost config: ErrorLog "| /path/to/vlogger -s error.log /path/to/logs" Or something along those lines. > Regarding error log contents, I do > have shell access, but it would be nice to provide a web interface so > that the developer can see the errors at least. I don't know of one specifically, though it wouldn't be difficult to create such an interface (by watching log files or receiving entries directly as described above, and then pushing them to the user with AJAX or something). Of course, having your developers do development locally (where they have access to the error log) and then pushing working versions to the production server is probably not a bad idea, and would minimize the amount of access they need to production logs. -- Jeremy R.

Re: [us...@httpd] Apache hangs on reload
Okay, so here are the salient lines from the error logs (I have two vhosts, webmail and wiki, running through suexec – if I put them through the regular FCGI process without suexec, I don't have this problem). 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 bui...@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.

[us...@httpd] Apache hangs on reload
Hello: I'm running PHP inside suexec with mod_fcgid and a couple wrapper scripts, and though it works properly, Apache now hangs whenever someone issues /etc/init.d/apache2 reload (which happens fairly frequently). 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 rootroot 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.
