Hi Robert any update on the core I posted? Re: [smartos-discuss] KVM VM Crashing, Core analysis Help ?<https://www.listbox.com/member/archive/184463/2016/09/20160916163414:EB650BAC-7C4C-11E6-94E8-DA2D75E01411>

I ran the coredump and it appears to be virtio network driver that’s causing the crash. At least that’s what it looks like to me. Let me know what you think. Here is the output: debugging core file of qemu-system-x86 (64-bit) from ab4fa5b1-de93-42aa-9072-b7a9b84265f4 file: /smartdc/bin/qemu-system-x86_64 initial argv: /smartdc/bin/qemu-system-x86_64 -m 6144 -name ab4fa5b1-de93-42aa-9072-b7a9b8426 threading model: native threads status: process terminated by SIGABRT (Abort), pid=45351 uid=0 code=-1 fffffd7fffded080 libc.so.1`_lwp_kill+0xa() fffffd7fffded0b0 libc.so.1`raise+0x20(6) fffffd7fffded100 libc.so.1`abort+0x98() fffffd7fffded190 vnic_receive_iov+0x2fc(f6c260, fffffd7fffdf5400, 2) fffffd7fffded230 qemu_vlan_deliver_packet_iov+0xe0(182b101f0, 0, fffffd7fffdf5400, 2, f67140) fffffd7fffded2c0 qemu_net_queue_deliver_iov+0x72(f67180, 182b101f0, 0, fffffd7fffdf5400, 2) fffffd7fffded350 qemu_net_queue_send_iov+0x92(f67180, 182b101f0, 0, fffffd7fffdf5400, 2, 4edb11) fffffd7fffded3c0 qemu_sendv_packet_async+0xbe(182b101f0, fffffd7fffdf5400, 2, 4edb11) fffffd7fffdf9440 virtio_net_flush_tx+0x19b(1810abc10, 182b0ee30) fffffd7fffdf9480 virtio_net_tx_timer+0x8f(1810abc10) fffffd7fffdf94d0 qemu_run_timers+0xb0(f625a0) fffffd7fffdf94e0 qemu_run_all_timers+0x51() fffffd7fffdff570 main_loop_wait+0x480(0) fffffd7fffdff5a0 kvm_main_loop+0x119() fffffd7fffdff5c0 main_loop+0x17() fffffd7fffdff900 main+0x2da4(30, fffffd7fffdff928, fffffd7fffdffab0) fffffd7fffdff910 _start+0x6c() Sent by John Barfield <john.barfi...@bissinc.com<mailto:john.barfi...@bissinc.com><mailto:john.barfi...@bissinc.com>> at Thu, 8 Sep 2016 13:32:52 +0000 Greetings friends, I have a VM that crashes once every day or every other day. There are no errors in the VM logs….it just shows that it may have lost power. In the GZ I’m getting VM core dumps. Could someone point me in the direction of the documentation or towards a tool that would help me analyze the VM core dump to determine why it is crashing? This is a windows server 2008 r2 sp2 VM for the record. GZ: is joyent_20151104T185720Z Thanks!

I would run something like mdb -e '::status;$C' /path/to/core/file. If you can share those outputs, we can likely tell you what happened and if this is a known bug. Please note that there have been many importa nt bug fixes and security fixes since that version, so I'd encourage you to update, but we should make sure that this is root caused regardless.
