2006-12-14 23:43:13 1Gv5qD-0007TH-UQ == [email protected] <[email protected]> R=virtual_user T=virtual_localdelivery defer (-9): failed to lock mailbox /var/spool/virtual/abc.com/info (lock file) or (fcntl/flock).

Check the directory shown to see if there's a lock file in there for that user. If there is, remove it.

By default DA uses one mbox file for holding all the mail in an inbox.

So you can't have to processes (reading and writing) to an mbox file at the same time.

So the POP3 and IMAP servers lock and unlock the file as required.

Somehow a process got killed before it could remove the lock.

(Using a lock file is the easiest way to lock and unlock a file in a multi-process or multi-user system; I've been using lock files as semaphores since the early 1970s.)

Temporary delays; they stay on the server in the queue waiting for the lock to go away.
