PA-3050 stops processing traffic

Has anyone had a PA-3050 stop processing traffic? Our PA-3050 started dropping all traffic today (internet access, DMZ, etc.), we failed over to the standby unit and were able to restore service.

Currently we have a support ticket opened but wanted to know if anyone here has had a similar experience. Thanks!

We are having similar issue. 3 times in 2 weeks primary 3050, running 5.0.8 stops passing all traffic in v-wire mode and won't fail-over automatically. We forced fail-over to passive box, rebooted fw1, and failed back to it just to have it happen again a few weeks later. We are currently pushing all traffic through the backup 3050 until PAN comes up with recommendation, or fix.

I've had this happen several times as well, last one today. We also have a HA cluster, and the primary (and active) firewall suddenly stops routing traffic, and the secondary (passive) does not try to take over, and acts like everything is OK.

Had to reboot the primary firewall for the secondary to become active, and I would like to avoid this happening again.

I've sent tech dumps to our support contact, so hopefully I'll get a better answer than "I'm sure this won't happen again" this time. Running 5.0.11, by the way.

Hello As-mg,

Could you please verify PAN brdagent log through CLI command and verify if matching with below mentioned symptoms.

A. PAN> less dp-log brdagent.log

1. Error message like : "need to reset ocelot link as XX error packet seen"

2.  link flap messages similar to above.

3. XGE link error.

4.  Check system logs for critical logs indicating “DP packet descriptor leak detected  on slot 1 dp0” or similar.

Jumbo frames are not active for our HA links. Forgot to mention that this is a 3020 cluster.

After contacting support their best suggestion was to update to 5.0.12 or 6.0.2.

I have upgraded both to 5.0.12 tonight, but I have a feeling that the bug fixed in 6.0.2 better describes our situation, so I will upgrade the firewalls to 6.0.2 tomorrow.

Fixed in 5.0.12/6.0.1: When High Availability Active/Passive peers lost communication on HA1 and HA2 links, a race condition caused the dataplane to restart.

Fixed in 6.0.2: Fixed an issue with PA-3000 Series devices where traffic could stop passing through the firewall or the dataplane could restart due to an internal path monitoring failure.

Hello As-mg,

It's recommended to run the signature pattern matching (AHO) on software

> debug dataplane fpga set sw_aho yes

We had this happen on a 500 running 5.0.10.

At the weekend the box spontaneously rebooted - according to support "They've seen it happen with 5.0.x and have no idea why" - there was nothing useful in the tech support bundle so right now we're just waiting to see if it happens again.

I had the same situation on a 500 with 5.0.11 one week ago. Device restarted suddenly without any reason in logs

Apparently we had encountered the same behavior on our 3020 cluster running 6.0.0. The device stopped processing any traffic and there was no evidence of what happened in logs. Restarting dataplane seems to be a working solution for us, yet i'd like to know what was the cause.

I also did verify dp-log brdagent.log as HULK mentioned above and we had these messages:

- Flapping Ocelot link 1

- Error: poll_func(3000/osprey_oct.c:164): Need to reset ocelot link as 51 error packets seen!

Does it mean i should run debug dataplane fpga set sw_aho yes command on our boxes or simply go for 6.0.2?

Hello Marcin,

I would recommend you to set the pattern matching on software (> debug dataplane fpga set sw_aho yes), instead of PAN OS upgrade.
