I'm having an oddball problem with locking. Mutt 1.3.24i on RedHat 7.2 Linux 2.4.16. The mailboxes in question are mbox format on an NFS server running Slackware 8.0 Linux 2.4.16.
When attempting to write to a box (say, <s>ave a message), I get: Couldn't lock /home/rnbwpnt/MAIL//spam? I get this error if "spam" is zero-length (touch spam), or if it contains one or more messages, or if it doesn't exist and I confirm create. I do not get locking problems on Maildir boxes (everything except this is Maildir, and I need mbox for this one application). There are no obvious conflicts in /var/lock/. Manually operating on the file in question (rm, mv, cp) produces no errors. Looking for pointers on where I might be going wrong. Searching for "lock" in the mutt manual at mutt.org produced only a note about how Maildir doesn't need it, and set dotlock_program (which is in the default location). Thank you. ag
