No. The accounts receive most of the deliveries just fine. Then inbetween the successful deliveries, some fail with that error message.
Maybe this has something to do with GPFS?
Could be. I'm not sure.
That error happens if maildir-uidlist.lock file was found to exist for two minutes + 2 seconds, and within those 2 minutes it changed at least once.
The uidlist is locked while maildir is being synchronized. With local filesystems syncing a 22k maildir takes less than a second. I don't know with GPFS. You could try this with for example expunging a message and seeing how long it takes to return "OK".
Using thunderbird, expurging a message seems to work just fine, and it takes less than a second.
Or maybe GPFS caches uidlist.lock file's existence similar to NFS attribute cache?
Could be something like that.
