Hello list,

when reloading dovecot via "doveadm reload" it throws me tons of errors like this: Feb 08 10:57:30 server1 dovecot[18243]: Feb 08 10:57:30 imap: Error: net_connect_unix(/run/dovecot/auth-master) failed: Resource temporarily unavailable Feb 08 10:57:30 server1 dovecot[18243]: Feb 08 10:57:30 imap: Error: net_connect_unix(/run/dovecot/auth-master) failed: Resource temporarily unavailable Feb 08 10:57:30 server1 dovecot[18243]: Feb 08 10:57:30 imap: Error: net_connect_unix(/run/dovecot/auth-master) failed: Resource temporarily unavailable Feb 08 10:57:30 server1 dovecot[18243]: Feb 08 10:57:30 imap: Error: net_connect_unix(/run/dovecot/auth-master) failed: Resource temporarily unavailable Feb 08 10:57:30 server1 dovecot[18243]: Feb 08 10:57:30 imap: Error: net_connect_unix(/run/dovecot/auth-master) failed: Resource temporarily unavailable

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
