Hello,
I am getting a persistent seg fault while trying to sync our server to a new location.
We are on 2.2.33.2, due for an upgrade but we have used dsync successfully in the past. In fact, we used it to populate this same instance. So I hope this is just a configuration issue.
My logs are being filled with these errors::
2019-07-10T08:29:53-04:00 localhost dovecot: [ID 583609 mail.crit] doveadm: Fatal: master: service(doveadm): child 44707 killed with signal 11 (core dumped)
On the remote we see:
2019-07-10T10:17:24-04:00 localhost dovecot: [ID 583609 mail.error] doveadm: Error: read(111.111.111.111) failed: EOF (version not received)
I tried doing sync manually:

I saw the note in the wiki about "dovecot --hostdomain" so I made sure they do not match.
The new target (z-imap2) was built using a zfs clone from the source (z-imap1). I changed the 'hostname', 'instance_name", and 'mail_replica' fields but otherwise they are identical.
Did I miss something?
Thanks,
Tony
