My kernel already has: maxusers 512 options "NMBCLUSTERS=9000" options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT options IPFIREWALL_DEFAULT_TO_ACCEPT options DUMMYNET >of course it should not crash, and of course it would be great if you >could investigate more on the problem if it is easily reproducible for >you. I've tried really. The only trend I see is if it's being used, it crashes. If it' not being used, it's perfectly stable. >Another possible source of problems could be that buffers reference a >route (descriptor) Aha. Could this have anything to do with the errors I'm getting? Jan 9 13:11:48 freebsd /kernel: rtfree: 0xf4822a00 not freed (neg refs) I searched the mail archives, but found no real result about this. However, these errors don't usually happen near the crashes.
