I've run into a strange problem; I have a mail server running Linux 2.2.13 (Intel Platform) on which the mail spool resides. Originally, we had it on a SunOS system, but the 2GB partition limit of SunOS was too restrictive so we moved it to a Linux box.
We also have a SunOS box that is a shell server that mounts this spool via NFS and people access it via various mail clients that manipulate the spool files directly such as BSD mail, mutt, mh, elm, and pine.
Mutt now hangs when you fire it up and it is hanging on an fcntl call that attempts to check for a remote lock on the spool file for the user reading mail. It hangs indefinitely and can't be killed even with kill -9.
It appears that remote locking isn't supported by the Linux nfsd and there is no lockd. Is there a fix for this problem? I know we could recompile some of the mailers to use a different locking method but I can't stop users from compiling things that do this and jamming up the machine with stuck processes that can't be killed. I don't see any flags in SunOS to disable locking.
