Re: Replication failed 3.0.5 -> 3.0.13, now 3.0.13->3.0.13

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

Apr 21 02:24:46 ifs sync_client[12656]: IOERROR: zero length response to 
MAILBOXES (idle for too long)
Apr 21 02:24:46 ifs sync_client[12656]: IOERROR: zero length response to
