[mpich-discuss] Problem with "sock"-channel

After reconfiguring, recompiling and reinstalling mpich2 with the sock-channel flag (--with-device=ch3:sock) to avoid active polling, every MPI program (Self written programs, and also the Intel MPI Benchmark too) breaks when it calls a MPI function:

1) Error at my self written MPI program:

2) Error at the Intel MPI Benchmark:

So I hope someone of you knows what issue is causing these errors.
