I was trying to run a case for a while (3M cells, pimpleDyMFoam, parallel by 4) and it was always giving me trouble after a while--pressure taking way too many iterations, time step blowing up, etc. I turned off writeCompression and it's now stable. Has anyone else ever encountered this problem?

Greetings Pete,
That's an odd situation... the only thing that comes to mind is some sort of memory leak that is damaging the memory locations where the fields are stored, which might be damaged while OpenFOAM is using ZLib to compress the data on-the-fly. A few questions:
