We did this immediately after the power came back after the crash,
epsecially because our time server didn't reboot correctly without
manual help. 

-- but yesterday we recognized that we forgot to check the time on one
fileserver out of eight!! It had a ntpd running but that didn't
recognize that the time server after its rivival.  

It was not an afsdb server, it just serves a readonly replica of an
application data volume which is needed by our AFSroot
installation. This volume is also readonly availble from another
fileserver which had a correct time. This must have been the reason
for the random behauviour (works -- works not -- works ....)

Now it is working again.
