i don't know since when but every time my computer starts to lagg and my memory and/or disk is working 100% my MC-Server crashes. this happened in my self compiled R1001 and R1004.
http://www.mediafire.com/?022x67skb76j14n here is the pdb the crashdump etc.
Try changing the fluid simulators from Floody to Classic, if it helps. I have a feeling the Floody simulator is still faulty and it definitely causes a lot of HDD and CPU action, because it floods large areas.
I'll have a look at the crashdump later in the day.
but i was not doing anything with water.
The crashdump doesn't say anything much, it is the small crashdump with almost no data other than the stack trace. So I know unloading a chunk failed, but the reason is in the stars. The big crashdump wouldn't have helped much, though, because this is probably a memory-overwrite issue - someone somewhere is writing in memory that doesn't belong to them. The hardest bug to find.
