random freezups -- how do i track down the problem?
 
I'm running KDE on top of 2.4.22k6 or 2.4.25k6 (depending on whether or not I want sound - no alsa drivers for 25 last time I checked). I'm on debian unstable / libranet cedar. In the last 10 days, the system has started freezing up at random intervals. I suspect I have downloaded something close to the core that is causing the freezeups, but have no idea how to isolate it. Drastic action would be to rebuild the system (from my Libranet 2.7 install CD) but this seems overly painful. Is there a good way to track this down?

Thanks

OK, these are the last lines before a freezup in /var/log/messages.
europa is my computer's name. 209.204.169.* is my ISP. Are these relevant? If not, where else should I look? Thanks

It looks like your rejecting packets. Maybe your being ddos'ed?
