I've said in multiple threads that the override_function() in /home/override.php error may or may not have anything to do with this issue but from my experience they came at the same time.Unfortunately with the issue beeing intermittent, and not always present, this makes it a bit tricky to find the cause for. Also the tasks the error comes up for varies a lot. At times it comes just by loading a page, other times it only comes when you actually do some major tasks, such as running a table optimization on the database, yet another time the table optimize runs without hitch so there's no concistency to why it would come up.
I have MediaWiki running on my site, which has database activity. Level server. And I've been having slowness and 503 errors, as well as the error.log reporting /home/override.php errors.Anna said:Do you have any database activity on your site?
