Hi All, We had 15 imap/pop UW-imap servers behind load balancer and mail storage was NFS for almost around ~30,000 users on it. Currently we migrate UW-imap to dovecot with fcntl NFS locking. After migration on dovecot it started error related locking see following error Error: fcntl() failed with mbox file /home/w/a/wahmed/.inbox: No locks available Error: fcntl() failed with mbox file /home/e/d/edurand/.inbox: No locks available Look like my NFS locking getting overload or something its (netapps NFS server) what you suggest to fix this issue ? how uw-imap was working with NFS before ? Appreciate your help. -S
