Hi,

I upgraded to 3.0.13 but it didn't help.

This time it copied about 18GB

in the logs I still see:

1 - inefficient replication

2 - IOERROR: zero length response to MAILBOXES (idle for too long)
IOERROR: zero length response to RESTART (idle for too long)
Error in do_sync(): bailing out! Bad protocol

But I have no idea what can I do next and why it fails

Hi,

I'm running 3.0.5.

I want to migrate to a new machine. I set up cyrus-imapd 3.0.13.

The replication started but it didn't transfer all mails.

The store isn't big 44GB, transferred was about 24 GB.

In the logs I see:

Bad protocol Apr 20 15:29:09 ifs sync_client[24239]: Processing sync log file /var/lib/imap/sync/log-run failed: Bad protocol

I also executed thereafter sync client manually:

/usr/local/cyrus-3.0.5/sbin/sync_client -r

but nothing changed, in the log appeared:

Apr 20 15:37:23 ifs sync_client[27304]: Reprocessing sync log file /var/lib/imap/sync/log-run

The directory /var/lib/imap/sync/ on master is empty.

The directory /var/spool/imap/sync. on replica is also empty

What can I try to get it woring? Is there a serious problem with replication in 3.0.5? I wanted to avoid upgrade on the old machine.

Best regrads,

Olaf Frączyk
