My PA2020 has 2 agent working identifying my AD users... but the mgnt plane is running 100% all day long...

Any suggestion ?

pls find below the show resources output....

5.x seems to require more management CPU utilization altogether than 4.x did. That shouldn't be surprising to anyone, given all the new features. We can hope that efficiency will improve as the 5.x code matures.

However, 5.0.2 (and 4.1.11) seem to have a very clear bug related to the User ID process consuming excessive resources.

Honestly I wish PA would slow down on the new features and beef up the stability/QA. It seems like we upgrade on support's advice to fix bugs and then after we upgrade we find other bugs... it's bug whack-a-mole.

Yes it doesn't get easier to recommend software versions for our customers.

Very disappointed that 4.1.11 seems to have the same bug, especially since they released that version some time after that this bug was known in 5.0.2.

I was thinking the exact same thing. I'm pretty annoyed to be rolling a box back from 4.1.11 to 4.1.10 tonight _after_ I rolled it back from 5.0.2 to 4.1 a couple weeks ago.

It's time and time again for us with PA... I like the "distruptive startup" nature of the company and all the features packed into the boxes they sell (and the complete lack of dealing with the insane licensing scheme of Check Point), but these QA issues are making it hard for me to make a case with my management to move forward with handing off more load to the PA boxes we have, especially since the Check Point firewalls we have in production seem to just hum along and "just work."

We're "dipping our toe" into Palo Alto slowly, and honestly these "bug whack-a-mole" issues are causing us to reconsider our firewall strategy.

Don't even get me started on the GlobalProtect client...

It is surely harder to get to get extremely high stability when dealing with some many things simultaneously, than it is just checking simply ACLs, That PAN has been able to do what it does so effectively is impressive now matter how you look at it.  I continue to be very very impressed with the product (of course as a partner I am biased I suppose), and wouldn't recommend anything else given the current threat landscape, but I will be taking a less aggressive approach to updating firmware for a while. I tend to try and keep on the current release under the idea that I _should_ be keeping my bug exposure down. I pushed our various boxes up through all the 4.1.x releases with no ill effects and was lulled into overconfidence I suppose. I suspect most people in these forums would say "what do you expect running the very latest release"...

We're sticking with 4.1 on a pair of our PA devices and we're still running into bugs. Not trivial stuff either... things like PA's implementation of DHCP doesn't work correctly (ticket open for a month and a half), GlobalProtect doesn't work correctly/crashes/throws errors (client and gateway)

We've got a ticket that's been open for two months for User-ID mapping not working correctly (on 4.1 code), where we basically can't use the 'user' column in our rulebase. That's a major feature that we can't take advantage of.

It's not "oh another customer is complaining and whining"... it's features that are advertised as working that weren't tested or that get broken by bugfixes.

I suppose your mileage may vary though.

Same issue here with 5.0.2 and PA 2050.

Hello again,

Seems like an hotfix is out for 4.1.11 to fix this problem.

You need to contact support to get it.

It seems PA dismissed its QA team (maybe in favor of copyright lawyers) and customers are responsible for all the testing now.

I can get the management backplane to calm down a bit by restarting useridd via the following command:

debug software restart user-id

Unsure how long it takes for useridd to get angry again after that.

Well, you just answered my question - rolling back to 4.1.10 as I type.

> PA: How does this stuff get past the QA process?

More to the point - if it's a known issue which is being reported by lots of people, why do you have to log a fault to get access to the hotfix? Why doesn't PAN just release the hotfix for general distribution with a release note which specifies that it's only to fix the issue listed? This jumping through hoops to get fixes for known, impact-inducing bugs is extremely annoying.

And when I *did* log a case, the first thing I get back from the support partner is "We've escalated it to PAN for release of the hotfix, but why don't you update to 5.0.1 instead"?

And rolling back *again* after installing the "hotfix" 4.1.11-h1 because it bloody breaks the HA sync between my peers.

This is beyond a joke, Palo Alto. Does *nobody* QA these things in all possible environments before release?
