If you quit and restart the problem gkrellm, does it start back up showing reasonable
values?   And could you try monitoring that server with a gkrellm on a Linux box to
see if it's that the server stops sending the disconnect data or if it's a problem with
the Windows client gkrellm.   If you were running a Linux gkrellm client I would
suggest collecting debug internet connection data by running:

    $ gkrellm -s server -d 0x1000 | grep "^+0\|^<inet>\|-0" > logfile

but I don't know if you can do something like this on your Windows box.
