Hi all. Some problem with free. I`ve got such mess in log: Jan 4 22:47:09 fs kernel: Fatal trap 12: page fault while in kernel mode Jan 4 22:47:09 fs kernel: fault virtual address = 0x3e Jan 4 22:47:09 fs kernel: fault code = supervisor read, page not present Jan 4 22:47:09 fs kernel: instruction pointer = 0x20:0xc060cc24 Jan 4 22:47:09 fs kernel: stack pointer = 0x28:0xe529ac30 Jan 4 22:47:09 fs kernel: frame pointer = 0x28:0xe529ac34 Jan 4 22:47:09 fs kernel: code segment = base 0x0, limit 0xfffff, type 0x1b Jan 4 22:47:09 fs kernel: = DPL 0, pres 1, def32 1, gran 1 Jan 4 22:47:09 fs kernel: processor eflags = interrupt enabled, resume,IOPL = 0 Jan 4 22:47:09 fs kernel: current process = 9 (thread taskq) Jan 4 22:47:09 fs kernel: trap number = 12 Jan 4 22:47:09 fs kernel: panic: page fault Jan 4 22:47:09 fs kernel: Uptime: 4d0h37m10s Jan 4 22:47:09 fs kernel: Physical memory: 2013 MB Jan 4 22:47:09 fs kernel: Dumping 243 MB: 228 212 196 180 164 148 132 116 100 84 68 52 36 20 4 Jan 4 22:47:09 fs kernel: Dump complete Jan 4 22:47:09 fs kernel: Automatic reboot in 15 seconds - press a key on the console to abort Jan 4 22:47:09 fs kernel: Rebooting...

This machine has been working for about 9 months with no problems.... but I dont know how to correctly find the problem. uname -a: FreeBSD fs.ngc.net.ua 8.0-CURRENT FreeBSD 8.0-CURRENT #3: Mon Dec 31 05:07:25 EET 2007 root@fs.myhost.net.ua:/usr/obj/usr/src/sys/FS i386
