Hi, I'm using dovecot 2.2.9 with a director/backend setup. The user base is about 4711 users currently.
If I start at one of the directors
doveadm search -A all savedbefore 5000d
it terminates with
doveadm(1rrissma): Error: doveadm server disconnected before handshake: EOF
doveadm(1rrissma): Error: 2001:638:913:f33::5:ff:24245: Command search failed
for 1phaaman: EOF
doveadm(1rrissma): Error: doveadm server failure
doveadm: Error: Failed to iterate through some users
The backend logs about that

Fatal: master: service(doveadm): child 11235 killed with signal 11 (core dumped)
Is this a known behaviour and fixed already, or do I need to do more
investigation?
(PS: Running the same command on one of the backends works w/o failure)
Best regards from Dresden/Germany
