This started with a problem with Maple which we have on a file
system which is nfs mounted from a server. This worked fine
until recently, but now on some of our systems, maple has
a problem when invoking help. We've isolated the problem
so that it no longer is specifically a maple problem except
that for some odd reason maple is trying to lock the help
What happens is the following. We are running RH6.0 on our
server with a 2.2.12 kernel and the knfsd-1.2.2-4 nfs server
package. From machines running RH5.2 and kernels 2.0.36 or earlier,
we appear to be able to lock files in the nfs mounted directory
using a fcntl call. But on machines running RH.6.X and more
up to date kernels, we can't. However, for a directory
mounted from another server, running RH6.0 and a 2.2.5 kernel, we
can lock files.
Can anyone enlighten us as to what is going on?
