PA-5050 (8.1.11) 100% Dataplane CPU (DP1)

Hi everybody,

 

We got two Palo Alto 5050's running in an active-passive configuration. We run three separate vsys. During working hours we see our dataplane exceed the 80% cpu util. Our dataplane DP0 shows a load of around 40% but our DP1 is maxing out to 100%. We tried disabling all logging and next gen funcionality but it's still maxing out to 100%. Does anybody know what could be going on? packet descriptor (on-chip) is also under heavy load on the DP1 while the DP0 is quiet...

Hi,

 

https://docs.paloaltonetworks.com/pan-os/8-1/pan-os-admin/zone-protection-and-dos-protection/dos-pro...

 

Can you try run the following command, and identify the session to check if the traffic is intervsys traffic?

Go back to that link above, in follow the step 2, and check if those sessions from

show running resource-monitor ingress-backlogs, are offloaded or not

 

ff that session is not offloaded, that is the problem, where it causing problems on that specific DP..

Hi NextGen,

 

Firstly thank u for your time and effort.

 

I checked a couple of sessions and most of them where offloaded and some of them are not. It's not one specific session that keeps appearing. Each time i execute the command "show running resource-monitor ingress-backlogs dp 1" different sessions appear.

 

Mostly i see sessions coming from our two HTTP forwarding proxy servers. Could it be possible that the Palo Alto experiences difficulties accepting so much sessions from only two hosts. About 4000 people connect trough these proxy servers to internet.

 

Some specific sessions take 10% CPU.

 

And why does DP1 shows 100% and DP0 only 40%. Shouldn't it be evenly distributed?

***  I would contact TAC to see if they have some better suggestions.

 

Q0:  how many sessions are generated by "RANGER_Prx-FTP-HTTP-HTTPS-01-02" ?  

Q1: Does rule "RANGER_Prx-FTP-HTTP-HTTPS-01-02" have threat, wildfire, SSL decryption, URL enabled?  

Q2: Can you try write an application override rule for  "RANGER_Prx-FTP-HTTP-HTTPS-01-02" , that will bypass all Layer 7 inspection.

 

Based on the rule name, it is allowing FTP, HTTP, HTTPS traffic.  It will be interesting to see the session counts during peak hours.  Since many of those HTTP and HTTPS sessions are short live and it could be high frequencies. 

 

>> And why does DP1 shows 100% and DP0 only 40%. Shouldn't it be evenly distributed?

 

It has to do with the DP hashing algorithm,  since DP0 already needs to handle new session creation on 5000 series.  I believe to 5050 only has 2 DP.  That is pretty much the best it can do.

Hi,

 

Thank u for your reply.

We already contacted TAC (through our supplier) and awaiting their response after collecting data. We already temporarily disabled all next gen firewall capabilities on all rules en disabled all logging on all rules. It did not help.

 

Could it be that the hashing algorithm sends all sessions to DP1 based on the source IP of the proxy servers?

 

Maybe it could help if we bypass the proxy servers so all clients will connect directly?

DP0 has dual tasks, function for new sessions creation and as a regular DP.    If the hash algorithm ( I never got a clear answer from PAN how the session distribution works on the 5000 series)  is favoring DP1, that is all.

If you can reduce the # of sessions on the firewall, that should help..

 

You can also try app override for that firewall rule, that may help as well

Well,

 

I would expect the firewall could handle this easily. The PA5050 has a troughput of 5 Gbit for next-gen. We are only handling 1 Gbit of traffic at the moment and ~220000 sessions.

 

Bypassing the proxy will only result in all the clients connecting directly to internet so it would not matter on the number of sessions i'm afraid.

 

The traffic of one user flows 4 times trough the firewall (2 different VSYS) before reaching the internet. First to the proxy (2x) and then to the internet (2x). Maybe we should optimize this traffic flow so it will only pass 2x though the firewall.

 

U are talking about app override. But if we disable all next-gen scanning on a rule this would do the same right? We already did this tot test if it would impact performance.
