you could try enabling pag garbage collection
sysctl -w afs.GCPAGs=3D1

This will cause afs to (once an hour) scan all running processes to find=20
out which pags have processes in them, and purge the tokens and connections =

(which I think is the problem here) belonging to pags that have no members. =
