Good Day, I get a panic on latest RELENG_6 every 6-12 hours. The server is a Dual Xeon FSB800 with 2 GB RAM and aac(4)-disks running postfix and amavisd-new for SPAM scanning. kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode cpuid = 3; apic id = 07 fault virtual address = 0x104 fault code = supervisor read, page not present instruction pointer = 0x20:0xc06774e1 stack pointer = 0x28:0xe4f93c90 frame pointer = 0x28:0xe4f93c9c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eglags = resume, IOPL = 0 current process = 5 (thread taskq) The panic always in process "thread taskq". db>trace _mit_lock_sleep(cb031e5c,c63f7180) at _mtx_lock_sleep+0x9d unp_gc(0,1) at uno_gc+0x222 taskqueue_run(c6439d80) at taskqueue_run+0x13f taskqueue_thread_loop(c09f8988,e4f93d38) at taskqueue_thread_loop+0x92 fork_exit(c06a1bc0,c09f8988,e4f93d38) at fork_exit+0x71 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp=0xe4f93d6c, ebp = 0 FreeBSD mx.local 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #1: Tue Nov 28 02:12:58 CET 2006 root@mx.local:/usr/obj/usr/src/sys/SMP i386 Does that look like a hardware problem or a software issue? I will try to swap RAM in the next few days. Best Regards, Markus
