Kernel Panic

LostInIgnorance

I won't get to testing that box (p4 dell gonna kick it in the parking lot) till tomorrow morning, so I'll have to get back to you on the test.

The snapshot with the fixes Jim mentioned is now up, I've upgraded all my systems to it and no issues. Granted I wasn't seeing any panics previously either, so those who can replicate issues, please test.

So far so good using this morning's build - tinkered around with the web gui for awhile with no crashes (couldn't even log in before…), did the same with a shell connection (which always crashed after a few minutes before) and am 1/4 of the way through transferring a 1.25GB file through the vpn to the pfSense box via SCP with no crashes so far. (It has always been communication directly with the remote pfSense box through the VPN that triggered crashes for me). Fingers crossed...

I am curious though - and I'll (dis)qualify this by saying that I am not a developer, nor do I pretend to fully understand much of the goings on in the git repository, but - I don't see anything in the list of commits since the last snapshot I tried that I would have expected to have an impact on this particular issue. Any idea as to what was causing the panics in the first place?

Look at the commits to the tools repo, not just the pfSense code repo. The tools repo is where things like kernel patches and builder changes happen.

Thanks, jimp, I had no idea! Adds a whole new level of excitement to the daily snapshots, doesn't it…

FYI, I have at this point - in addition to trying everything else that previously caused an instant panic - transferred a couple of gigs through the VPN to what I would have called my 'sick' pfsense box, and everything seems to be working and happy.

Yeah, those are the main two. There are also others that are used but they change much less often, if at all (like the freesbie2 stuff).

Sounds very promising. Keep trying to kill it, see what happens. :-)

Update to the 9th or later, it should be stable from that point on.

pwnell

Yep did that just now, will keep an eye on it. Thanks.

pwnell

Ran for 2 hours then everything just hung. No panic, nothing in /var/crash and no crash message after reboot. Keyboard / everything was frozen, no traffic was allowed through the device.

jimp

Any idea what you were doing at the time? FTP? PPTP?

pwnell

I had a VPN connection open (PPTP), but not really much data transfer. Not much more - I was not doing anything other than the IMAP/SMTP/SSH/HTTP traffic.

1 hour, crashed:

Just reporting my experiences -
Running 2.0-BETA5 (i386) built on Wed Feb 9 00:54:34 EST 2011 on both machines. (Did a clean install)
uptime = 7+ hours

Testing CARP & failover, FTP traffic, OpenVPN client/server setup.

No crashes so far, and they used to be pretty easy to produce.

This is only a simple test environment, so it doesn't get regular traffic, only a single client at a time for now.

I'm getting a panic in today's snapshot, 2.0-BETA5 (amd64)
built on Wed Feb 9 19:39:50 EST 2011 . This was caused I believe by syncing to slave. I was in the process of setting up a new interface on the master and configuring a vpn to it.

This is master or slave?
That seems like an impossible trace but i will look at it after the information.

geewhz01

This is on the slave. I've not had any problems on the master with this, just the slave.

Thanks,

Andy

We also need the output of "bt" at that prompt. Also, is this i386 or amd64?

Will do the bt at the prompt next crash.
