How reproducible:

100%

Steps to Reproduce:
1. bring up the RDMA hosts mentioned above with RHEL8.7 build
2. set up RDMA hosts for mvapich2 benchamrk tests
3. run one of the mvapich2 benchmark with "mpirun" command, as the following:

timeout --preserve-status --kill-after=5m 3m mpirun -hostfile /root/hfile_one_core -np 2 mpitests-IMB-MPI1 PingPong -time 1.5


Actual results:

Expected results:

Normal execution of benchmark test with stats output

Additional info:

Same behavior exists on RHEL-8.6 builds
Comment 1 Brian Chae 2023-07-21 16:35:13 UTC 
On RHEL-8.9 build, RHEL-8.9.0-20230718.23, for CTC#2 test, mvapich2 running on CXGB4 iWARP device failed in the following way.


==============================================


1. Some benchmarks passed
2. A lot of benchmarks failed with RC139 or RC255, as the following:
