Some vos commandos didn't finished like
vos listaddrs
vos examine root.cell (with tokens active)

vos examine root.cell -noauth (sometimes finished, sometimes didn't)

Some clients couldn't start AFS services.

I have restarted all vlservers with active write transaction doing:
bos restart -server $server -instance vlserver -localauth

This seams to fix all the problems.  For the record if someone else is
in the same situation.
