2.5.7 -> 2.5.7 initial replication fails - failed to parse?

[Karl Pielorz]

Hi,

I have 2 * 2.5.7 servers. The first is setup to replicate to the other 
(which is currently empty). The 'master' has quite a bit of mail on it 
(~90Gb).

As it's quite a lot - I brought up the replica, but left 'rolling' 
replication off.

On the 'master' I then ran:

  /usr/local/cyrus/bin/sync_client -v -A


This started chugging away through all the mailboxes - but then failed:

Apr 20 16:24:59 syncserver[17103]: twoskip: checkpointed 
/vol/data/imap/mailboxes.db (304 records, 60352 => 56864 bytes) in 0.016 
seconds

(error 14)
Apr 20 16:25:04 kernel: pid 17103 (sync_server), uid 60: exited on signal 6


If I re-run the 'sync_client' command as above, it fails again at the same 
point (just after starting out).

The directory in question ('/vol/data/imap/spool/sync./17103') has 
1,517,996  files in it - but none are called 
'9e4cb1ca93123a15dc49d84a9c7a9a60841a1079'.

Can I safely remove all of '/sync./*' and start the replication again? - 
Anything else I can do to either fix / troubleshoot this?

As far as I can see "user.mailbox.CantProcess 1" on the 'master' doesn't 
exist (i.e. there is no '1.' message file on the underlying file system). 
Nor, on the replica. The mailbox looks "mostly" replicated - the next 
message up (if it's doing them in numerical order) would be the file '27.' 
- and that file looks unremarkable.


Thanks,
