Dear Jan,

I found the place, where my server hangs in Lock (???)
for the problem I described in the last problem report.
All packets sent by client and server get through without
problem. (I flood-pinged the link for 30min with no loss)

IMHO the symptom comes from

    SLog(1, "ViceGetTime for user %s at %s:%d on conn %d.",
         client->UserName, inet_ntoa(client->VenusId->host),
         ntohs(client->VenusId->port), RPCid);
    if (!errorCode && client) {
      SLog(1, "ViceGetTime before lock");
      /* we need a lock, because we cannot do concurrent RPC2 calls on
       * the same connection */
      SLog(1, "ViceGetTime after lock");

As long as my vice/venus are playing reintegration with backfetch,
the ViceGetTime call from venus via cfs cs will not get through this
point. Venus will beleave in a disconnected server then.
Do you have any clue for me, what puts the long duration
WriteLock during reintegrate?
