Can you send us the smallest chunk of code that still exhibits this error?

Hi all,
I get the following error when I try to run a simple application implementing a ring (each process sends to rank+1 and receives from rank-1). More precisely, the error occurs during the call to MPI_Finalize():
Assertion failed in file src/mpid/ch3/channels/nemesis/netmod/tcp/socksm.c at line 363: sc->pg_is_set internal ABORT - process 0
Does anybody else also noticed the same error?
Here are all the details about my test: - The error is generated with mpich-3.0.2 (but I noticed the exact same error with mpich-3.0.4) - I am using IPoIB for communication between nodes (The same thing happens over Ethernet) - The problem comes from TCP links. When all processes are on the same node, there is no error. As soon as one process is on a remote node, the failure occurs. - Note also that the failure does not occur if I run a more complex code (eg, a NAS benchmark).
