Error bursts

[Sir Osis of Liver]

Seeing this again, different forum, different errors than previously.  Server logged 10.6 mb errors in two seconds this a.m., same thing last night around 23:00.  Starts with a lot of these -

Server error_log was over 42 gb yesterday when they reported problems with the forum.  Deleted it last night, two error bursts since.  Forum is currently logging just a few errors, mostly from mods.  Any way to determine which scheduled task is causing this?

Hmmm...Don't think I've seen those before.  Not sure they're tied to scheduled tasks.

I would compare time stamps on the scheduled task log to the time stamps of the error.  I would also look closely at the web access logs during that time for the corresponding activity.

Bet you it's the daily notifications digest.

Pretty urls had been uninstalled at some point, but left a lot of code in QueryString.php.  Will see If I can clean it up.
