dsync-trouble

Wed Nov 3 19:22:31 UTC 2021

Hi,

dsync and replication are failing. They used to work, so I guess, it
might be related to the update to 2.3.17.

This is a fresh install of Freebsd 13.

Please let me know, if further Information is needed (I haven't follow
Odhiambos advice from another thread yet, but will follow, if requested)

With replication-plugin disabled:

# doveadm sync -u xxx at zzz.de tcps:mail.bruecko.de
doveadm(xxx at zzz.de): Panic: file array.c: line 10
(array_idx_modifiable_i): assertion failed: (idx < array->buffer->used /
array->element_size)
Abort

enabled plugin (btw: what makes dovecot trying to sync accounts on a
fresh install, though the other server isn't configured to replicate
with freebsd.bruecko.de):

Nov  3 19:08:28 freebsd dovecot[68537]:
doveadm(x.zzzz at yyy.de)<91733><IT8dBxzQgmFVZgEAA4a8sQ>: Fatal: master:
service(doveadm): child 91733 killed with signal 6 (core not dumped -
https://dovecot.org/bugreport.html#coredumps)

I didn't follow Odhiambos advice from another thread yet, but do, if
requested.

Any help appreciated
