I think all of the panics are happening as various network apps are tearing down their connections. I've had it trap while in the kernel on the behalf of fetchmail, ppp, and nfsd (when I kill -9'd nfsd to try to make sure I wouldn't panic during a buildkernel, and during a shutdown.). This happened with both my LAPTOP kernel and the GENERIC kernel. Last kernel built before today : Aug 9 11:55:25 laptop /kernel: FreeBSD 4.6-STABLE #25: Mon Aug 5 18:37:34 EDT 2002 Aug 9 11:55:25 laptop /kernel: root@laptop.lambertfam.org:/usr/obj/usr/src/sys/LAPTOP Kernel with problems : Aug 9 15:39:09 laptop /kernel: FreeBSD 4.6-STABLE #26: Fri Aug 9 14:56:21 EDT 2002 Aug 9 15:39:09 laptop /kernel: root@laptop.lambertfam.org:/usr/obj/usr/src/sys/LAPTOP And I am now running a kernel, LAPTOP, built after cvsuping with date=2002.08.09.00.00.00 I have survived a shutdown -r with this kernel and have now checked my mail several times. On the basis of that, :-), I'm going to claim that this kernel is ok. I suspect that the tcpip related changes today are to blame for my problems.

Rather than copy and paste all of the dmesg and trap information into this message, I'm going to upload my messages logs to : http://www.lambertfam.org/~lambert/laptop/messages/ This URL: http://www.lambertfam.org/~lambert/laptop/ has all the gory details of the configuration of this system. The machine seems to be able to run as long as I want it to as long as I don't hit the network. I have done three buildkernel with it while the bad kernels were on it. Some network apps don't seem to bother it. I was able to cvsup a couple of times. First to see if I had cvsuped mid commit and secondly to back my tree up to midnight. -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
