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 5000dit 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

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)
For dovecot with LDAP we make this
After fix dovecot-ldap.conf
user_filter = (&(objectClass=posixAccount)(uid=%u)(BackendHost=backend1.wibble.net)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) # For using doveadm -A: iterate_attrs = uid=user iterate_filter = (&(objectClass=posixAccount)(BackendHost=backend1.wibble.net))
Work perfect
doveadm: Error: Failed to iterate through some users
Need more search limit in LDAP http://dovecot.org/list/dovecot/2016-February/103118.html
