Hi guys, My linux CentOS 4.5 postfix is misbehaving, from time to time I keep on getting the below error and during that time any account copied in the mail or is forwarded mail by that account gets multiple repetition of the same mail until delivery is made to the mailbox having a problem. Error: (cannot update mailbox /var/mail/foo. for user foo. unable to lock for exclusive access: Resource temporarily unavailable) Help!!!
It can happen that some other process (e.g. Postfix) is currently accessing the mailbox, and then you cannot fetch mails from it until this other process is finished.
This is happening during delivery of mail to mailbox Feb 6 16:01:20 mail postfix/local[26248]: D84D34511F8: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=71, delays=25/6.3/0/39, dsn=4.2.0, status=deferred (cannot update mailbox /var/mail/foo for user foo. unable to lock for exclusive access: Resource temporarily unavailable)
output of ls -la /var/spool/mail drwxrwxr-x 2 root mail 4096 Feb 12 16:31 . drwxr-xr-x 18 root root 4096 Oct 8 15:35 .. -rw------- 1 as mail 1179 Jan 21 10:55 as -rw------- 1 ast mail 55877822 Feb 12 16:31 ast -rw-r--r-- 1 root root 223360024 Feb 8 13:15 backup -rw------- 1 da mail 9151 Feb 12 12:36 da -rw------- 1 foo mail 3443748 Feb 12 16:31 foo -rw------- 1 e mail 0 Feb 4 10:09 e -rw------- 1 eu mail 37306 Feb 12 09:58 eu
That seems like a race condition to me, use lsof to see what application has opened the file and is not releasing it.
The mail box is being locked by a blackberry device which pops mail from it. Is there a way of configuring the black berry or the mailbox to avoid this conflict
The blackberry is on imap actually. I don't understands how it locks the mailbox such that postfix is unable to access it. Is there a way of making postix superior per se to the blackberry device over the mbox
