Dont't know if it matters, but this account has 22000+ messages .. The other one I saw with the same error message had 15000+.
BTW. What filesystem do you use?
We're using GPFS.
But it doesn't happen always I guess? Maybe this has something to do with GPFS?
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".
Or maybe GPFS caches uidlist.lock file's existence similar to NFS attribute cache?
