In our system test setups with NFSv4.1 mounts, we keep hitting this RHEL client bug where
under some unknown condition client fails to send RECLAIM_COMPLETE_OP after client id
expiry and recovery. And ganesha keeps sending NFS4ERR_GRACE indefinitely and this client
will hit timeout on all the OPENs and hence halting the system testing.
We upgraded to RHEL7.7 but still issue persists. I tried searching in redhat bugs but do
not see any outstanding issues about this. Is anyone else here facing this issue? Do we
know if this is really a RHEL client issue?

We had discussed this before in this community and ganesha behaves as per RFC, so we dint
do anything:
