a server most erroneous

February 22, 2010 2:39 PM

My site crashed with a 500 - server error after accruing a 2GB+ error log filled with "unable to load dynamic library'. Help me figure out the cause.

Apparently my server is throwing a ton of errors, but I have no idea what is causing them, looking at my error_log it is just filled with this:

[22-Feb-2010 09:42:14] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-zts-20060613/homeloader.so' - /usr/local/lib/php/extensions/no-debug-zts-20060613/homeloader.so: undefined symbol: executor_globals_id in Unknown on line 0

Any clues?

Best answer: Well, I found this forum post asking the exact same question you are. I even thought it might be you, looking for help somewhere else, but it's ten months old. Are the answers on that page helpful?

Step one: since the error messages are coming so rapidly, tail the log (tail -f /path/to/your/error_log) and then in a separate console start killing applications (or at least restarting them) one at a time until the error messages stop.

Once you've narrowed it down to a single application, troubleshooting (or at least seeking help in the correct location) should be much easier. It certainly looks like WordPress is the problem, however, so you might want to set a cronjob to dump the log every hour (or change your logging level to show errors instead of warnings) until you hunt this down.

Response by poster: Gah, thanks tWPL. I googled a line or two out of my error log but didn't seem to find anything. Once I saw that post I took a look at my php.ini file and commented out the improperly loading extensions.

I have no idea what hose extensions do, but if everything seemed to be working when they weren't loading I guess that means they aren't essential.
