Hello Paul, is there the chance of storage hardware failures? Or VPS I/O issues in case it is on a VPS?

Hello group, Since a few days I have massive problems with lockfiles blocking the mailboxes (type storage, /var/mail/user). don't know if it's the right list. may more concern dovecot. postqueue is full of 944C223FC2 17905 Fri Mar 28 06:02:01 XXX (cannot update mailbox /var/mail/pane for user XXX. unable to create lock file /var/mail/XXX.lock: File exists) XXX 6530223FC9 3597 Fri Mar 28 06:11:46 XXX (cannot update mailbox /var/mail/XXX for user XXX. unable to lock for exclusive access: Resource temporarily unavailable) XXX and messages get delivered, but after ages. most of the time lsof /var/mail/XXX shows one to two processes of dovecot/imap There were no configuration changes at the point the problem started. Do you have ideas or tips how to debug this further? or should I look for a dovecot mail list? Thank you Paul
