The machine is a p166 with 32 megs of ram. It has two Linksys LNE100TX 10/100mbit ethernet cards. Before I enabled NAT on this machine, it had one of these cards in it, for normal LAN usage. I had no problems in that enviroment. Here is a trace from the latest crash: Debugger(c02a0dbb,c3286f00,c050f880,c33f5f50,c017f4d7) at Debugger+0x42 panic(c02a23d2,c3286f00,c050f880,820f144,c33f5f70) at panic+0x74 sbappendaddr(c3286f44,c02f9630,c050f880,0) at sbappendaddr+0x2b div_input(c050f880,14,c050f880,8169bc,820f144 at div_input+0x12a ip_input(c050f880) at ip_input+0x69f ipintr(c024dab3,0,27,27,820f144) at ipintr+0x4b swi_net_next() at swi_net_next coredumps and my debug kernel, or anything else you would find useful are available upon request, I do not know how to submit them with this interface. I apologize if I am doing anything wrong in submitting this, I have only been using FreeBSD for a couple of weeks, and am ignorant of official protocols and procedures. >How-To-Repeat: The problem repeats itself at seemingly random intervals. It apparently has nothing to do with load, or network traffic, as I have transferred several hundred megabytes of data over FTP without a hitch, only to have it crash while I checked my email. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
