I've been using the TV command line interface (tvcli) to grab program stack trace and memory information for a stalled or hung MPI job using a script that monitors the progress of the job. As this stalled or hung state happens only intermittently if at all, the script does this automatically.

The location of the code where the stall happens is consistent and is within a MPI_Allgather.

Is it possible to access the MPI message queue data via the tvcli in the same manner as the stack, memory and thread state information ?
