While we usually see the process that is preventing Pine from opening
the mailbox, in this case we do not know wtf process is holding it up.
From the .pine-debug file(s), we see:
.pine-debug1:IMAP 15:13:04 10/16 mm_log warn: Mailbox is open by another
process, access is readonly
I went on my own and tried to open a single INBOX in two different
sessions and naturally got the process ID that had the INBOX opened. A
check on this specific user's current processes revealed that no other
process with her UID was running Pine, there is not lock file in the
INBOX directory, the spool directory is empty, the permissions on the
incoming mail directory is set at 1777, and even SIGHUP'd sendmail. All
to no avail and again, it is a curious thing that this is happening to
only one user. Should I delete their .pinerc and have them run and
reconfig? Or do you have another idea on how to resolve this error?
Thanks for your attention to this matter.
