Hi,

 I wanted to upgrade our Nameservers to bind-8.2.2p5 and have a problem
when stopping/restarting our nameservers. When i stop the server and
immediately start it again, i get the following errors in the logfile:

17-Nov-1999 11:13:44.803 default: There may be a name server already
running on 195.180.210.2.54

 (I'm using Port 54 so i can stop and start the named as i wish without
increasing our named downtime..)

 I checked the source and increased the number of retries the named will
take to rebind to the interface. That helps but increases the starting
time of the named to ~6 minutes.

 It seems to me that the named is not cleaning up when he is shutting itself
down. After i stopped the named there still show up connections if i check
netstats:

 Using bind-8.1.2 this problem does not occur. All connections are closed
as they should be and i cannot find anything in netstats after shutting the
named down.

 Any suggestions?

Thanks,
Andreas
