Status update:
as per the logs, this issue is caused by the resent replay request during recovery, but MDT doesn't find the corresponding reply
of the resent request, and It could be related to the Multiple Slots in last_rcvd. Still analysis the related code lines to find where
the problem is and will update the status once there is any progress.

Let's close the ticket as cannot report and reopen if we do see it again

This issue has not been seen on any branch since 7/24 and may have been resolved by related landings. We are going to reduce the severity and leave it open.

I don't remember having seen this test fail during my local testing.

However, I have to admit that the kernel I use does not include the dev_read_only patch, which means the MDT device cannot be made readonly by replay_barrier. This means the test environment is not exactly the same.

Hi Gregoire, have you seen any problems similar to this in your testing?
