The U-version VLDB volume record retrieved by the VL.GetEntryByNameU rpc op carries a change counter (the serverUnique field) for each fileserver listed in the record as backing that volume. This is incremented whenever the registration details for a fileserver change (such as its address list). Note that the same value will be seen in all UVLDB records that refer to that fileserver. This should be checked before calling the VL server to re-query the address list for a fileserver. If it's the same, there's no point doing the query. Reported-by:
