I testing cyrus with a NFS storage by two *identical* cyrus + postfix servers Both /var/spool/imap and /var/imap are mounted by both servers ( the socket directory is moved out of the mount) Everything seems working fine but I find sometimes dupelim doesnt work. I tried to debug , I get errrors like these in my maillog DBERROR: skiplist recovery /var/imap/deliver.db: ADD at E2C8 exists What could be the reason ? I am using cyrus-imapd 2.3.7 on centos 4.4 on both servers , with a NetAPP box for storage Thanks Ram ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
