ezjail jail migration
Has anyone tried to migrate ezjail jails between 7.2 and 6.4? I've read it works fine 6.4 - 7.2, but what about 7.2 - 6.4. Is there any chance I could get away with this by not being forced to reinstall all the running stuff - proftpd, apache? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Crash dump freebsd 7.2
I have several jails running on my freebesd machine and lately it started to crash when it gets a bit loaded. I followed the freebsd kernel debugging manual, and got some output, but I have no idea what to do with it. The only thing I think I understand of it that the bit that matters are just the two last lines. Is there anyone that can help? # kgdb kernel.debug /var/crash/vmcore.2 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

7.2 dying with Kernel Trap 12
My 7.2 FreeBSD server has started to crash with kernel trap 12. I googled around and most of the topics I found were about faulty RAM or other harware problems. This is VMware vitual machine so I see no way of hardware problems as we even tried to move the machine around VMware nodes to see it's RAM. It worked absolutely fine for about two months, but now sometimes the server lives for up to 5 hours, sometimes it panics in 10 minutes. Is there anyone that can help me to resolve the problem? Here are few errors on crash: kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode cpuid = 2; apic id = 02 fault virtual address= 0x10 fault code = supervisor read, page not present instruction pointer = 0x20:0xc07d4a21 stack pointer = 0x28:0xc72dec1c frame pointer = 0x28:0xc72dec30 code segment = base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process= 36 (sctp_iterator) trap number = 12 panic: page fault cpuid = 2 - Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address= 0x6e727598 fault code = supervisor read, page not present instruction pointer = 0x20:0xc08bf945 stack pointer = 0x28:0xc72bfaa8 frame pointer = 0x28:0xc72bfacc code segment = base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process= 30 (em1 taskq) trap number = 12 -- kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address= 0x10 fault code = supervisor read, page not present instruction pointer = 0x20:0xc07d4a21 stack pointer = 0x28:0xc73e29c4 frame pointer = 0x28:0xc73e29d8 code segment = base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process= 9020 (libssl.so) trap number = 12 panic: page fault cpuid = 0 Uptime: 25m37s Thank You Zete ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
