I’ve been trying to figure that one out, but since it typically only happens after a couple of hours of continuous testing I’ve yet to find the culprit.

This patch at least makes the rpc.gssd daemon stop crashing - which when that happens will make all further NFS (with sec=krb5) client stuff fail miserably (not good if that happens on a user login server…)

I’ve resent the patch according to your instructions now.
