PAN OS 8.1.5 - Thoughts?

L2 Linker

Hi there! Has anybody had the chance to play with PAN OS 8.1.5 yet in Production? Are there any noticable issues? I've been locked into this killchain of bugs ever since we made the leap to 8.1.0, and I'm just wondering if this build will be the "stable" release.

So I'm seeing issues with URL Filtering blocking URLs that are allowed by policy as "allow" or "alert" in 8.1.5. I've got a ticket open, and I'm just waiting on support.

Support requested I upgrade from 8.1.1 to 8.1.5 because of an issue we had. I was really worried after reading this but so far I have had no issues with 8.1.5.


Just my 2 cents so far. 🙂


8.1.6 is recommended. 🙂

We moved to 8.1.5 and one week later to 8.1.6 because Data Plane CPU usage raises to 90-98% at production time (PA 3060).


At the moment, support suspects about SMB deep packet inspection but we need to clarify the issue. With 8.0.7 Data Plane CPU usage was 30-60%.
