After looking into the issue, our team has recommended that you try using a newer version of MVAPICH2, such as 2.3.6, and see if the issue persists. Version 2.2 is several years old at this point. Please let us know if that fixes your issue once you have tried
it, and thank you for reaching out for help!</div>

<div dir="ltr">Hi Mvapich team,</div>
<div dir="ltr"><br>
I have a small compute cluster of 20 nodes,using mvapic2-2.2 on Inifiniband fabric, and there is only a single MPI process on each node. I am trying to debug a weird issue - occasionally, the slave node will get a stale/old message from the head node, instead
of the actual message sent at that time. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Question : I would like to enable basic and verbose logging of MPI communication to help debug this issue. What option should I add to the 'mpirun_rsh' command line to get it ?.... and do the logs show up on the shell directly ? <br>
<br>
I already tried adding <span style="font-family:New; font-size:medium">MV2_DEBUG_FORK_VERBOSE=1, but don't see any extra logs.</span></div>

<div dir="ltr">Appreciate a prompt response.</div>
