dovecot -n

26 Jan 2022


      Hi all,
I am using dovecot-2.3.17_1 on FreeBSD system.
This server offers webmail, pop3 and imap access for users.
Today I am receiving several complaints from users about slowness and/or access issues.
I checked on my /var/log/maillog and I see lots of:
Error: Timeout (180s) while waiting for lock for transaction log file /var/domains/domain.it/username/Maildir/dovecot.list.index.log (WRITE lock held by pid 84939)
Error: Corrupted transaction log file /var/domains/domain.it/otherusername/Maildir/dovecot.list.index.log seq 2: indexid changed: 1643184505 -> 1643205059 (sync_offset=0)
Error: Transaction log file /var/domains/otherdomain.net/otheruser/Maildir/dovecot.list.index.log: marked corrupted
Not all users seem affected. My mailbox, for example, is working fine.
I checked on my disks (this is a ZFS volume) and I didn't find errors/warnings.
Any suggestion?
This is my dovecot configuration:
dovecot -n

Thank you very much
