I check the logs for the last failure, and see that at the
same second two servers were trying to deliver separate messages
to the same account. I'll try avoiding a bit of these parallell
deliveries by changing MX to prefer one host. That might help as
a workaround, but might fail next time this preferred host is
too busy to process all requests..
That really sounds like the problem then is with GPFS, perhaps it has
some internal caching that doesn't work as Dovecot expects.. Maybe
Dovecot v1.1 with mail_nfs_*=yes settings would fix it too (I know it
helps FUSE filesystems like glusterfs).
