I'm running into inconsistent errors from sync_client on a Cyrus 2.3.16-8 system. It's driving me crazy because the same sync_client command will succeed at some times and fail at others. I know others are running similar and much more complex systems successfully, so I must be missing something simple or fundamental.
Thanks in advance, John When the problem occurs, sync_client gives a "do_client(u...@example.com): bailing out!" error and logs a message about failing to reset the replication (cyrusadmin) account. This occurs both when running sync_client against a single user and when using sync_client with a file containing 27,000 user names. The failures do not always effect the same users, and attempts to replicate a given user generally succeed after 1-5 tries. When running the 27,000 user test the failure can occur for anywhere from a handful to a few hundred users. The problem occurs whether sync_client is run by root, by root "su -c"' to cyrus, or as the cyrus user. Running "reconstruct", "reconstruct -G", or "reconstruct -x -f" prior to running sync_client does not resolve the problem. In addition to the "do_client(u...@example.com): bailing out!" failures, users are sometimes skipped without a sync_client error message -- they simply aren't replicated on that pass. Sync_client displays the line "USER u...@example.com" but none of the ADDSUB lines, similar to when processing a user that has never used their mailbox. Both problems occur whether or not rolling replication is running. Both the master mailstore (eml-store04) and the replica (eml-replica04) are CentOS 5.4 64-bit servers running as virtual machines on a single ESXi 4 server. They are using the ext3 filesystem. The cyrus-imapd and cyrus-imapd-utils RPMS were built from the Invoca RPMS on a similar system. I enabled SNMP support, but didn't make any other changes to the spec file before running "rpmbuild -ba cyrus-imapd.spec". No errors were reported during the build. The data was transferred from a Cyrus 2.3.7 system using rsync on /var/lib/imap and /var/spool/imap, and appears normal from a Cyrus and IMAP client perspective. Between tests, I clear the replica with "rm -rf /var/lib/imap/domain/* /var/lib/imap/sieve/* /var/spool/imap/domain/*". Everything under /var/lib/imap and /var/spool/imap is owned by cyrus:mail.
