[mpich-discuss] Program Crash

[jarray52 jarray52]

Hi,

My code crashes, and I'm not sure how to debug the problem. I'm new to
MPI/mpich programming, and any suggestions on debugging the problem would be
appreciated. Here is the error output displayed by mpich:

[proxy:0:1 at ComputeNodeIB101] HYD_pmcd_pmip_control_cmd_cb

I'm using MPI_THREAD_MULTIPLE over an ib fabric. The problem doesn't occur
all the time. I believe it occurs during a recv statement, but I'm not
certain.

Thanks,
Jay
