Well, I think this deserves its own thread.
My admins appear to be stumped by this problem that has been plaguing the server for a long time. It has gotten FAR worse recently since the FTL 2.0 launch, resulting in the server being down for hours at a time.
They have tried many fixes, but the problem has not gone away.
According to Dan, "Some code, or sequence of code, is causing a PHP process to hang."
Trying to figure out what code that is, is apparently not an easy task. Would love to hear some ideas on how to address this.
