I have Threads 6.5.1 running on an Apple Xserve Dual G4/1.3Ghz with 2GB RAM and OS X 10.4.3 Tiger. About every 24 to 36 hours, my board shows nothing but a white page regardless of the page I'm trying to access. When I view the MySQL process list, there are 100 or more processes related to the Threads database, and most of them are locked. I increased my max threads from 100 to 256, but the problem persists.

Where should I start diagnosing this issue?
