[Dxspider-support] Crash insight?

I had the same problem at SK3W-6.
The cluster was hanging about 15 minutes. Niticed it at two times, but could have happened more frequently. I happened when a user connected. Nothing special in the logfile.
Running Linux FC2.

At roughly 1100Z on Sunday morning, my cluster hung for a while.  My node is
running on SuSE Linux 9.2.  Some of the telnet connections and all my node
links went down and I could not connect via telnet.  I was able to log in to
the node via SSH.  Netstat showed that one IP address was flooding the node
with connection attempts to the spider port.  At about 1120z, the cluster
came back without rebooting.  I am attempting to contact the user that
flooded the telnet port to try and find out what he was using for software
to connect to the cluster.  It appears that it went wacko.  All of the
connects were in the LAST_ACK state.  Dirk, does this ring any bells?

I will try and get more information on the source of the problem and post
it.

Is this a windows telnet problem? Would running Lee's (VE7CC) telnet proxy
program be an idea here? I say this because I have never had it crash during
CQWW and, further, can't see how a user program would cause the problems you
are experiencing. But then I don't run windows, so what do I know?
