fcntl: No locks available (errno = 37)

[Dan Lipofsky]

I am using mutt-1.0pre3us on Red Hat 6.1 Linux.  When ever I try to
save a message to a file on a network file system I get
        fcntl: No locks available (errno = 37)
If the file does not exist it successfully creates it but leaves it
length zero.  If I try to save to a file on the local file system it
works fine.  Can anyone help me out here?
