Fatal trap 9 in KVM environment
I'm running pfSense for some time now, since 2.0.something it has always been running without issues. With the latest 2.1 releases I'm very rarely running into crashes. Today I managet do catch one:
Fatal trap 9: general protection fault while in kernel mode [...] Stopped at rn_match+0x25: cmpw $0,0x10(%r13)
The VM is configured with VirtIO disks, emulated e1000 network cards.
Any hint on what it could be? Where to look at?
I'd suspect VirtualBox first, especially in light of their woeful QA practices. Don't try the latest 4.2.14 if you want your VMs to actually work.
I ge tthis with pfSense every now & then. A reboot usually fixes it.
Thanks but I'm not on VirtualBox, I'm using KVM.
Sadly this pfSense is in my office, where often nobody is there to reboot the firewall in case of kernel panic :(
This happens out of the blue? I've only ever seen it on bootup. I know jack about KVM, but it's the exact same crash that I see in VB.
On second glance, I think I was getting fatal trap 12, not 9. Are you running pfSense 2.1.4?
Yeah running the latest.
On other deployments I didn't upgrade above 2.1.2 I think and those firewalls are running since months.
Mine, always upgraded, has crashed twice since 2.1.3 (approximately)
Hmm no idea other than downgrading and then check stability over the course of weeks/months. Does KVM have any HA abilities, heartbeat checking, auto reboot on hang or anything like that?
not by itself, but can be implemented in some way.
Thanks for your support. I will try to gather the informations for a bugreport.
