Bi-Weekly(ish) crash - getDuration:0

[Alfiegerner]

I was runnning Sage 5 stably for a while now until recently my sage server started locking up hard once to twice a week.

When it does the logs show a stream of "getDuration : 0".

I don't want to post the whole file as it is 5.7 meg but towards the end of normal logging it runs like this

Fri 11/17 19:29:17.400 getDuration : 0

Is this just a symptom of the lock up or could it be part of the problem?

Also, does anyone know of any good logging / diagnosing software I could run on my sage server to help me identify the problem?
