I know it is a faq already asked on the community forums, but in this case it is especially related to this particular configuration: PAN-OS 9.0.4 on a PA-820.
Starting from the day I installed 9.0.4 on this machine, I see the management cpu always at 100%; the top 5 processes with higher cpu usage are the httpd and four pan_task processes, and I can't figure out if it is a normal behavior or not. I remember that when running 8.1.x there was not such problem.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10539 nobody 20 0 2453580 176216 7956 S 198.7 4.3 10646:37 httpd 3505 root 20 0 75960 22496 7620 R 100.0 0.5 31708:51 pan_task 3506 root 20 0 50780 7868 6840 R 100.0 0.2 31708:41 pan_task 3507 root 20 0 51624 9448 7472 R 100.0 0.2 31707:54 pan_task 3508 root 20 0 51624 9572 7544 R 100.0 0.2 31708:54 pan_task
The device is very low on network and resource usage, with as low as 10 users and less than 1000 cuncurrent sessions.
Is anybody experiencing the same issues with 9.0.4?
Hi @grenzi ,
pan_task are the threads in the dataplane, where the packets are processed , and they will always show values like 99% or 100%. It is a correct value meaning that the dataplane is busy processing all the packets that it receives.
As for the high httpd load ... you can try to restart the process and verify if it slowly rises without dropping which could indicate a memory leak issue.
Restarting the web-server process, as well all the management services, does not solve. I also removed all the EDL and reduced the logging. I'll try to downgrade to 8.1.
