dovecot 2.2.18 replication I/O Timeout

Dear list,

I am having an issue like this 
http://www.dovecot.org/list/dovecot-cvs/2014-September/024898.html with 
my current dovecot 2.2.18

Concret:

doveadm -Dv  replicator replicate -p high -f  info

throws an I/O Timeout error and the only thing I can see are some lock 
issues:  Error: Couldn't lock /var/vmail/info/.dovecot-sync.lock: Timed 
out after 30 seconds

Can I debug the communication one level deeper?

I replicate over a somewhat slow DSL connection.


I had the some problem with dovecot 2.2.9 and after upgrading to 2.2.15 
everything went smoothly, just a wild guess, maybe the timeout_reset was 
removed again?

Well, doesn't look like it: 
https://github.com/dovecot/core/blob/master/src/doveadm/dsync/dsync-ibc-stream.c 
or 
https://github.com/dovecot/core/blame/master/src/doveadm/dsync/dsync-ibc-stream.c


Some debug hints would be nice.


Thanks!


Jan
