I have configured a replication and sometimes it fails to work. In logs I have found the following errors: Apr 29 12:33:47 dsync-local(login@mail.org)<XuU3OWyf5VoXHAAA0J78UA>: Error: Failed to lock mailbox INBOX for dsyncing: file_create_locked(/var/spool/mail/mail.org/login/.maildir/.dovecot-box-sync.lock) failed: fcntl(/var/spoo l/mail/mail.org/login/.maildir/.dovecot-box-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by pid 5921) Apr 29 12:36:11 doveadm: Error: net_connect_unix(/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable Apr 29 12:36:12 doveadm: Error: net_connect_unix(/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable Apr 29 12:36:12 doveadm: Error: net_connect_unix(/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable Apr 29 12:36:21 doveadm: Error: dsync(localhost): I/O has stalled, no activity for 600 seconds (last sent=mail, last recv=mail (EOL)) Apr 29 12:36:21 doveadm: Error: Timeout during state=sync_mails (send=mails recv=recv_last_common) Also `doveadm replicator status` shows some failed request. I have not done any reconfiguration - only system upgrade.
