We've been having a problem where our database suddenly gets slammed and reaches it's max connection limit in the span of 5 minutes. It goes from ~20 connections to ~2500 in minutes. This could be the result of several things (like DDOS) but we are trying to investigate from a couple of different angles.
Is there anything Xenforo-wise that would possibly slam the database like this in a short amount of time? We have a ton of users and large tables so I was wondering if cron jobs or the new deferred system would possibly try running a bunch of queries at once (we just upgraded and are now seeing these issues).
Thanks in advance!
