mbox over NFS has *never* been recommended, it is unsafe - for any pop/imap type server, not just dovecot. If its not too late, and since you are testing a new server it cant be, change to Maildir, it was designed specifically for this very reason.
also should use: mail_fsync = yes mail_nfs_index = yes mail_nfs_storage = yes mmap_disable = yes
