Kernel Panic
-
(Ticket #KZZ-134399 opened)
I have the cluster in production for 1 day without any problem right now.
Here is one strange thing I've seen in the logs (on the slave) the other day, what happened?Feb 13 22:14:50 kernel: vip7: link state changed to DOWN

The next snap (building now) should have more carp panic fixes.
Not sure about the crazy kernel message there, though it looks like maybe it was two messages overlapping, but a bit more corrupt than that usually is.
-
I would like to inform that since its updating on Sunday (when the snapshot server was available again), the Dell P4 with the integrated em gigE, I have not recieved any panics and the machine is running well. Thank you all for all the hard work fixing the issue! :D

Hi,
Like cyber7, I'm getting kernel panics (pf_state_tree_id_RB_REMOVE_COLOR, pfpurge is always the current process) since two weeks (approx. 2 to 3 times a week) on a VMWare setup. Here's a screenshot :
-
spacelui,
amd64 or i386? snapshot date? What type of setup, CARP? Multi-WAN? anything special going on with FTP/PPTP? Any more detail might help. Posting the same panic that someone else had doesn't help much (unless you also have the bt output to go with it) but if we can track down what about your setup might be related to the panics, that would be more helpful. What we need is to find some commonality between the people still getting them.

Hi Guys.
I am still getting the same panic, just this time with a cmpl error. I am busy updating to the new snapshot, but why is it that after months of running fine, I am starting to see this panic?Kind regards
Aubrey Kloppers
ps - I am updating to the following snapshot:Auto Update Download Status
–--------------------------------------------------
 Current Version : 2.0-RC1
 Latest Version : Tue Feb 15 16:36:07 EST 2011 -
If it's a different error, it's not the same panic. We need the full text of the panic and the backtrace (bt at the db> prompt) in order to say anything.
But don't report anything until you've replicated it on the new snapshot you're updating to.
-
Thank you Jim.
ps - It was nice to chat to you yesterday. Do you not ever sleep :)Kind regards

Sorry, I cut the details…
It's a 2.0-RC1 of yesterday running on an i386.No multiwan, no carp and I have indeed some incoming pptp traffic going to a nated server on the lan. VMWare ESX setup. I do an upgrade every week, it began to happen on the 28th of january. I tried to look in the repo to see commits between 21st and 28th, to see if something relevant has changed, but a lot of things happened... plus, I'm not sure that couldn't happen before.
Next time it happens, I'll post the backtrace.
Edit : I reverted to the last backup I had before upgrading on the 28th, it's a Fri Jan 7 15:25:33 EST 2011 snapshot…

Hi Guys
look at my panic: http://forum.pfsense.org/index.php/topic,33403.0.html
and see if this does not solve your problemsKind regards

Hey Aubrey, changing my mtu's didn't fix anything. In fact it caused a panic on both boxes when trying to apply the changes. I don't think I will try that again.

Did you get the panic/crash info when it did that? Also, are you on i386 or amd64? What snapshot date?
-
No, I didn't. Sorry. But I'm sure it will happen again soon and I have the camera ready. I am running i386 and build Mon Jan 31 07:16:37 EST 2011 right now (saw the same issues with Mon Feb 14 02:12:45 EST 2011 and I can't remember which one from the 15th).
-
Update to the most current snap ASAP and then test again. Testing on old snaps isn't likely to provide any useful feedback for this. There were patches after those dates to help prevent panics in other situations.
-
I was able to make my CARP slave fail again (seems reproducable) - I was changing the mtu's back to default, if making one change and applying it things seemed fine, when I changed a few of them and applied them but applied changes after a few (maybe 5) then it hung.
I will update to the latest snap and see if I can make it fail again…
-
I updated my CARP backup to the latest snap - Thu Feb 17 02:14:25 EST 2011 - and ran through similar motions that caused the panics before with no issues. I have updated my master as well and will update if things fail again.

Can any of you with the pf_state_tree_id_RB_REMOVE_COLOR panic
try and set debug.pfpptpproxy=1 and see if they get the panic? -
Sure, let me now how to do it (sorry) and if I get the panic running today's snapshot that can be my next step.
-
Remember messing with the GUI when this happened, and then it stopped working… and then that.
-
Please give info on each screenshot you put in here.
Its absolutely required the date of the snapshot and how the box is cofnigured: carp, vlan, pptp,….@ acherman
Go to system->Advanced->System tunables->Click +(at the end)Tunable: debug.pfpptpproxy
Value: 1
Description: Testing pptp fixClick save and try to see if it panics still.
