<br>
Yes, but this information is also in the manual - I encourage you to take a look. You can search for "debug" or "debug_mb" to find the relevant commands.<br>
<br>
Thanks<br>

Anil,<br>
<br>
If you are able to reproduce this, it would be helpful to gather debug logs as described in the Lustre manual (I suggest starting with -1 debug on the client). As is, this is interesting but not something investigable without more info.<br>
<br>
Regards,<br>
Patrick<br>
