PfSense 2.3 LAN interface stops routing traffic - stops working after 2 or 3 day

jeffvfren

I'm having the same issue. Disable CPU cores, still under monitoring.
Hopefully the fix release asap.

Update:
It does not work for me, the issue just happen again.

Add us to the list as well.

We have a virtual pfsense cluster on our DRC site with and ipsec tunnel to our prod site. Since the update, we've had constant crashes from the master on the DRC site.

It has been stable for the past 2-3 days now, but with a VCENTER session open, I see a constant CPU usage warning on the master on the other side. We have done the CPU workaround too but as soon as we launch our VEEAM replications, we can be pretty much sure that the ipsec tunnel will fall. Def looks like all the UDP traffic is basically doing a DOS…

We're still working on tracking this down. Have it narrowed down to something in our IPsec changes (which are just back-ports from FreeBSD -CURRENT), but that's still 80 change sets potentially related.

Good to know you're working on it! :)

We also are having this problem with 2.3 , it happens each week.
We use multiple ipsec connections.
The pfsense is inside a vmware.
2Gb ram
4 cores

I think the state table size is also bigger: 82% (165500/201000)
When i want to open the state table it also crashes Allowed memory size of 268435456 bytes exhausted.
I will put more ram in the system when i have a downtime window.

–--
Yes i got my down window upgraded the ram to 4Gb, can now view the states without any problem.

Happened again today twice but with different details.

LAN went down. For whatever reason my script doing ifconfig down and up did not help. I tried manually with no luck. Retried and introduced longer sleep between down and up and then it worked. This was the first crash in several days.
appr. 60 minutes later LAN was down again. However this time I did not even manage to get any result on the serial console. I had to power down/up. No core dump I was able to find however after login I saw a crash and uploaded it. not sure if it is related. I would say it happened around the time of (1).

I have 5 locations and we use the Dell R210 servers all sites except 2 have this issue. Only difference between them are Internet Service Providers.

Site 1 R210 Charter Fiber no issues

Site 2 AT&T LTE charter fiber bo issues

Site 3 Charter Fiber issues every 2-3 days watchdog error no lan routing

Site 4 charter coax internet issues every 3-days

A other firewall of us got stuck just now, when i looked at the console it was showing a different wan adres.
It seems to have been reverted to a private, will take a screenshot next time.

cmb

We seem to have a fix for this. It's not yet merged into the source tree, but will be soon.

It's not universal or even close to it or we wouldn't have released with the issue. Not ISP-specific. Just happens the traffic profile of some systems will encounter it. Certain UDP streams is what triggers it.

Do you have an ETA?

Sometime this week.

Hello,

any news on this ? Is there a special setting or a patch to fix the issue available ?

Thx.

cmb

Reducing the system to one core is the only workaround. The fix was merged into devel branch today and hopefully into RELENG_2_3 tomorrow, in which case it'll hit snapshots tomorrow.

jonnyaalgaard.org

Then I have upgraded to the new snapshot that came this morning (2.3.1-DEVELOPMENT (amd64) - built on Thu May 12 00:18:20 CDT 2016 - FreeBSD 10.3-RELEASE-p2), and will check it out.
I have also removed the temp workaround, from /boot/loader.conf.local
The temp workaround for me were to add these lines into loader.conf.local
hint.lapic.1.disabled=1
hint.lapic.2.disabled=1
hint.lapic.3.disabled=1

When I entered these lines pfsense were stabile for me, but now I have enabled all cpu cores again, and hopefully the new snapshot will work just fine.
Before the workaround I did have 10-12 “crashes” a day.
I will post back if the new snapshot works Ok or not.

UPDATE! Before i managed to post this my pfsense crashed again with the new snapshot. I will try to disable all but 1 cpu core again, still using todays snapshot.

cmb

There is no fix yet, as I noted. Watch the bug ticket for updates.

cmb

The fix for this was merged this morning and is in the most recent available snapshot, Thu May 12 14:01:47 CDT and newer.

My test setups are around 4.5 hours run time in a scenario that never lasted more than 3-4 hours without the fix. Another user who had a circumstance that was much faster to replicate than anything I could duplicate in a lab (a matter of a handful of minutes, rather than hours) has also confirmed it's no longer happening.

Needs more runtime and more feedback from others, but initial results are good.

Those of you impacted, please upgrade to latest 2.3.1 (instructions here), remove the disabling cores workaround if you did that, and let us know how it goes.

OP here. Testing this for you now. It usually crashed on me within 6-12 hours but up to 24 hours was the latest. I should know no later than this weekend if it is working or not. I'll update you when I know more. Thank you!

cmb

My test environments are now over 11.5 hours and still running fine. That's 7.5+ hours longer than any affected kernel has lasted in the circumstance. Definitely seems to be fixed.

Any feedback from those impacted who upgrade appreciated.

This informs are in the front of the Firewall -> Rules -> .. page too.

Any idea to fix this ?

Thx.
