Crash Dumps - Consolidated List

[Gangrenous]

I am going to try to record every crash dump so that maybe I can narrow all of the causes down. It will help to record any patterns. This one happened after the server set idle for about 4 hours and happened during my login.

This is an interesting one, reproducible. Make a type 4 proc, have the target of the spell "pet" in your details of the spell. When going into combat, twice I have had this crash dump happen. I had the spell target type as pet.

What I think caused it was a misconfiguration of the LUA script.

AddProc(Target, 4, 100.0)

Should had been

AddProc(Caster, 4, 100.0)

Yes, it should never happen but some GM, somewhere will do it.
