Default Swap usage on parallel run

nikhilesh is on a distinguished road

I am running the cases on parallel processors with metis domain decomposition.

While the run starts, process start eating up RAM. But before the RAM gets exhausted, process starts using system SWAP space. And soon, SWAP usage reaches 100%. Is there any specific command which is limiting the RAM usage in OpenFoam run.

I was facing this issue with 5 million grid size on 128 processor. Please guide why this might be happening.

Thanks and regards
