PA200 process running at 100%

[Ante]

Hi there,

I've seen a task called pan_task taking up 100% cpu on two of my PA200's. Is this a PA200 specific thing? Not seen this on any other hardware platform, looking into it further it does not look like it's actually using 100% CPU, wondering if it's something to do with the single cpu architecture and splitting the two cores to backplane/management plane.

Any advice would be greatly appreciated.

Running latest threat, url and PAN OS 4.1.9

Hi...I recommend that you open a support case on this if the CPU remains at 100% for extended duration.  Thanks.

Hello,

Having pan_task run at 100% on a PA-200 is normal.  The pan_task process is the software dataplane which always runs at 100% when looking at the "show system resources" output.  To determine the actual load on the dataplane you could use " show running resource-monitor minute last 5".

Thanks,

Hi Kevin,

Many thanks for the reply! I did suspect that it was a "normal" behavior. I did look at the show running resource-monitor and didn't find it correlating. (thus posting here)
