Further to my last message, I've updated my master so now both servers report the same version: version : v2.4.17 d1df8aff 2012-12-01 I'd like to understand some error messages that I am getting and what I should do to resolve them... On the replica: syncserver[8816]: higher last_uid on replica user.myuser - 57628 < 57629 syncserver[8816]: higher modseq on replica user.myuser - 36186 < 36187 On the master: sync_client[5197]: MAILBOX received NO response: IMAP_MAILBOX_CRC Checksum Failure sync_client[5197]: CRC failure on sync for user.myuser, trying full update sync_client[5197]: SYNCNOTICE: record mismatch with replica: user.myuser more recent on master sync_client[5197]: SYNCNOTICE: master uid:57626 modseq:36180 last_updated:1359731641 internaldate:1359729048 flags:( NonJunk) sync_client[5197]: SYNCNOTICE: replica uid:57626 modseq:36177 last_updated:1359730649 internaldate:1359729048 flags:(NonJunk) sync_client[5197]: SYNCNOTICE: record mismatch with replica: user.myuser more recent on master sync_client[5197]: SYNCNOTICE: master uid:57626 modseq:36180 last_updated:1359731641 internaldate:1359729048 flags:( NonJunk) sync_client[5197]: SYNCNOTICE: replica uid:57626 modseq:36177 last_updated:1359730649 internaldate:1359729048 flags:(NonJunk) sync_client[5197]: SYNCNOTICE: only on replica user.myuser 57629 Despite these messages, my replication appears to be working but I can't as yet be 100% sure. I'd like to understand the above and try and stop them if I can... I can't find any documentation detailing what the above means, and I'm not that familiar with the internals of the imap server, so I'd really appreciate some pointers... Thanks very much. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
