Is this normal? It seems like dovecot mostly continues and plays through it, but there are a lot of errors in the logs about corrupted files.
v1.0 doesn't flush NFS caches, which can cause this if multiple servers access the same maildir at about the same time. http://wiki.dovecot.org/NFS has some explanations of this. v1.1 has mail_nfs_storage=yes (and mail_nfs_index=yes) which make this possible. Anyway best would be if you could just redirect the user to the same NFS server always, even with v1.1 it should give better performance.
