Hi,

I have two IMAP/LMTP Dovecot server in replica (version 2.3.4.1) for testing purposes, both connected through an IPsec tunnel, I use LDAP/AD for userdb, all seems to work fine except for these errors present in logs every day:

NODE A:

doveadm: Error: sieve: file storage: utime(/var/www/html/ooo/its-test) failed: Operation not permitted: 28 Time(s)
    dsync-local(its-test)<TxExKuQgeWHlTAAA045Smw>: Error: read(xxx) failed: Connection reset by peer (last sent=mailbox_delete, last recv=handshake): 1 Time(s)
    dsync-local(its-test)<fXcyHCd3eWGHXwAA045Smw>: Error: sieve: file storage: utime(/var/www/html/ooo/its-test) failed: Operation not permitted: 2 Time(s)

NODE B:

    doveadm: Error: Couldn't lock /mnt/mail-storage-dev/its-test/.dovecot-sync.lock: fcntl(/mnt/mail-storage-dev/its-test/.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds: 2 Time(s)
    doveadm: Error: Couldn't lock /mnt/mail-storage-dev/its-test2/.dovecot-sync.lock: fcntl(/mnt/mail-storage-dev/its-test2/.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds: 1 Time(s)
    doveadm: Error: sieve: file storage: utime(/var/www/html/ooo/its-test) failed: Operation not permitted: 28 Time(s)
    dsync-local(its-test)<QtV8HSh3eWHFDgAA/HgeEQ>: Error: sieve: file storage: utime(/var/www/html/ooo/its-test) failed: Operation not permitted: 2 Time(s)

What I have to do? Do I have to worry about this or I can ignore it?

Thanks

Regards
