...Enterprise 6. The mail store is NFS on a NetApp filer, the index files are on local disk. We have about 6000 total active users, though not all of them access the system at the same time. All goes well for a while, then we start seeing errors like this in the log: dovecot: imap-login: Error: net_connect_unix(imap) failed: Resource temporarily unavailable imap-login: Internal login failure (auth failed, 1 attempts) And at this point, users can't log in.
