Description Leonard Evens 2001-10-22 15:17:43 EDT

Description of problem:
We have been running kernels 2.4.2 and 2.4.3 under RH7.1.  We have had
/var/spool/mail nfs mounted from a server on various client machines so
they can share the mail spool files.  This has worked fine, but when we
upgraded to kernel 2.4.9-6 (for security as recommended by RH) we found
that programs like mail, mutt, elm, and pine encountered problems.  For
example, with mail, one can read the
mail but quitting causes it to hang.  We believe this has to do with
the fact that /var/spool/mail is mounted rw and these programs try
to lock the spool file.   So there is probably some bug relating the
2.4.9-6 kernel and nfslock.  When we go back to kernel 2.4.3, the problem

Version-Release number of selected component (if applicable):
Rh 7.1, kernel 2.4.9-6, nfs-utils-0.3.1-

How reproducible:

Steps to Reproduce:
1.Boot the mail server with 2.4.9-6.
2. mount /var/spool/mail rw from the mail server
3. run mail and try q to quit.

Actual Results:  mail hung and had to be killed with Ctrl-Z to stop it and
then killing the process.

Expected Results:  mail should have quit.

Additional info:

Similar things happen with elm, mutt, and pine.
