I not even sure that this is the correct forum to send is such a concern. Anyway, if someone has an idea what is wrong (could be as simple as requiring that I increase the size of a buffer table, or something) and how to fix it I would appreciate. I have used *bsd since about 1996 and really enjoy the robust networking functions. This is probably the first time I've had a problem related to kernel network problems, if that is in fact the case. Sorry if I sent this to the wrong place, al The task I perform: What I am doing is a network scan, sending pings (using ping) to a few million addresses. The pings come from an alias address on my interface, and have an individual signature in each payload (thus ping in place of nmap -sP). The symptom, After pinging almost a million addresses, my kernel panics. My script keeps a checkpoint of where in the scan I have completed, and when I start off from the checkpoint, the scan will continue further, but again my kernel will panic but this time after only a little while (a few (tens of?) thousands of pings). There are no records of any problems before the panic occurs, no references in /var/log/messages, etc. Corrective effort This first occurred in August. Once it failed, I cvsupped stable, built world, installed a new kernel. It still failed so I re-did all those funny things in UPDATING (like MAKEDEV all), mergemaster (the original system was installed in November 2000). The panics still occur in a repeatable fashion after updating with newest code Sept 5. So I configured dumpon, and build a kernel with debug support, after CVSuping to the most recent level ( morning Mon Sep 9 2002) and read quickly through the chapter on kernel debugging in the docs of FreeBSD, and collected some information about the crash in hopes that someone can help. I should have run a GENERIC kernel, in place of my kernel which is configured with IPFilter, ipfw, dummynet, smbfs, etc.., but I figure that my configuration should not be too uncommon so should there be a problem it should be resolved generically.
