Intermittent inet connectivity after updating to 10.2.8-h3

L0 Member

We're currently running on 10.2.3-h9 (PA-440's in HA pair Active/Passive) with remediation steps put in place for CVE-2024-3400 and Telemetry disabled. 

We attempted to migrate to 10.2.8-h3 as it is listed as a preferred release and fix for the CVE as listed by PA. The update process went as expected and everything appeared to be completely functional. After approximately 20-25 minutes of run time, we started experiencing intermittent internet connectivity. Some users were fine, others were not despite being on the same subnet space. After troubleshooting for a while with no identifiable cause, it was decided to move to 10.2.9-h1 and try again. Same results. Sporadic, intermittent internet access. 

We then rolled back to 10.2.3-h9 and no more issues. Has anyone seen this issue on either of those OS releases?

I can see that Palo Alto put 10.2.8-h3 as preferred, but I have seen several problems with this version. If your PA is an 800 series you should be fine with 10.2.7-h8.

If you already installed a more stable version that worked for you I would like to know what it is. Thanks

When you had experienced intermittent issues on the two previous versions (10.2.8-h3 and 10.2.9-h1) did you get a chance to open a support case in order to have TAC troubleshoot to see if they could find an underlying cause for the intermittent connectivity issues?
