So your using MVFS?

In any case the current RHEL-4 autofs v4 will have any changes that came out of that work. If you are seeing some other problem related to the kernel walking into directories when it shouldn't you probably have no choice but to update autofs and kernel and see if that helps. > > There are other with very similar messages, they all suggest a patch > which forces autofs to do a check of some sort. > I do not know how to implement the mentioned patch.

I haven't heard from Chris for some time now, not sure what he is doing.
