Hey everybody,

I am using a slightly modified version of dsmcFoam and OpenFOAM-1.7.1 on 4 cores and my simulation crashed with the following error code. I've never had any other stability-problems with the solver on my PC and I don't get too much information out of that error code. Could there be any problem with my hardware? The owner of the PC just told me, that there have been some problems with the stability of the PC because of some RAM-issues.

Error Code:
