Hi,
I know that a lot of work has been done regarding doveadm server, but I'm
still
experiencing easily reproducible segfault crashes of doveadm-server with 2.1.16
when running the following command in a 4 node director/mailbox cluster:
/usr/bin/doveadm -c /etc/dovecot-director/dovecot-director.conf -D purge -A
The dovecot-error.log shows the following errors (addresses anonymized):
