Hello list,
when reloading dovecot via "doveadm reload" it throws me tons of
errors like this:

I have searched for this timeout in dovecot config, but havent found something.
Can you tell me how to define this timeout, or is this an LDAP timeout in
userdb/passdb and dovecot-ldap.conf ?
Or better, how to prevent this failures?
I can see them sometimes in the log too w/o reloading.
Regards,
Daniel
