Pfsync kernel panic after 2.1.5 to 2.2 to Upgrade - pfsync_undefer_state
-
Great. We are trying to replicate this but are just seeing continuous error messages without the crash.
Do any of you have any special Limiter setup? Can you give any details?Steve

Marlenio,
Looks like the most recent crash report we have from that IP is Mar 3rd. Could they have come from a different IP?Steve

Hi steve,
213.215.138 is VIP of the first output array of pfSense (2 units HA mode). Master IP is 213.215.138.67, BACKUP 213.215.138.71. Let me know if you find it.Thanks in advance,

Nothing from anything in that /24 subnet since Mar 3rd. :-\

It 's very strange. I'm sure it was sent at least three times. :(

Can anyone tell us where that patch is, We are having the same issues when applying limiters with CARP and HA.
Thanks,
Tom
-
Yes, that patch is in 2.2.1 and has been in snaps since Feb.
If you are seeing this problem and are running 2.2.1 can you make sure you keep any crashreports and tell us what hardware you're running.
Thanks.Steve

I have to same problem when I upgrade Pfsense from 2.1.5 to 2.2.1…
Pfsense is running on virtualcenter 2.5. (Never had this before)
I tried twice, but nothing changed, this message is looping on the screen, and vm is using 100% CPU. There's no crash, but pfsense is useless.
I'm not using any high availability services (only limiters)
-
Yes, it's the same error on my carp 2.2.1 with limiters.

Steve,
I would really like to help but don't know how. Have you been able to reproduce the behavior? I am back on 2.1.5 now and could repeat the update process. Apart from the non-existing crash reports what else would you need or could be useful?
I have HA and limiters configured and pfSense runs on KVM/QEMU.
As mentioned before, I got "pfsync_undefer_state: unable to find deferred state" printed in the console after the upgrade process on the backup node (after reboot).
I got Mathiew's behavior when I tried to restore my 2.1.5 configuration from the backup node on a fresh install with 2.2.1. In both cases, I had to "physically" shut down the machine.

So we are able to replicate the continuous log spam but not any sort of crash. Though in our test the box remained running and accessible. We are looking for crash reports really but any info is useful.
Mathiew, you are seeing that on a single VM? No CARP/HA setup at all?
That's interesting. What NICs are you using? What limiters do you have defined?Steve
-
One VM only, I tried to import the config file on a fresh pfsense 2.2.1 install, but I had the exact same behavior.
No CARP/HA setup. I use a a lot of services, openvpn, ipsec, limiters.
I can send you my config file, if needed. I use E1000 adapter.

@stephenw10 Is there something i can provide to you to help out? We are using two physical machines running two Dell CS24s with dual cpus and 16GB ram each and these are our front line. This is a production environment so i wont be able to make a ton of changes but i can give you information. Just let me know what you need me to post.

If you see any crash reports then we want to see those.
Other than that it's odd that not everyone running is seeing the same thing. If there's something unusual in your config then maybe we can try to see a pattern.Steve

I repeated the upgrade process today after having disabled my floating limiter rules and it worked.
However, as soon as I enabled any of them the console didn’t stop printing "pfsync_undefer_state: unable to find deferred state". The first time I wasn’t quick enough in disabling the rules and the machine got unresponsive with no CPU load (no crash report).
After a reboot I was able to disable the rules and the machine stayed responsive. I then deactivated “Synchronize States” and enabled the floating limiter rules. Apart from the known “Bump sched buckets to 256 (was 0)” the console remained unchanged. As soon as I activated state synchronization "pfsync_undefer_state: unable to find deferred state" was back again.
In contrast to Mathiew I can choose whether to have either HA or limiters.
This was done on a backup node, the master still runs 2.1.5.

Thanks for that report flofogal. All data is helpful.

I removed my limiters rules from the config and it's working, no more psync error…
-
Mathiew,
I have seen one other incidence of this in a single box (not part of a HA setup). IN that case the box previously had a CARP config of some sort and had stray tags in the config file that had not been translated correctly across an update.
In that instance it was fixed by enabling HA sync, saving, and the disabling HA sync again. Limiters could then be used.Steve
-
Steve,
if you say "fixed" it means that limiters could be used without HA afterwards not together with HA. It is a solution to Mathiew's issue only. Correct?
Cheers,
Florian

I can try, but I never touch any HA/CARP services on this machine.
Thanks for your work.
EDIT : I reactivated limiters after doing that and no problem so far.
