High memory usage PA 3020

L0 Member

Hi, can someone help me? I have PA-3020, about 900 security policies, about 50 vpn tunnels (low traffic), I noticed high memory usage , What could be the reason for this? How can i relaease this?

I would say a TAC case would be in order. There could be something in the config or that version of the code that could be causing this.

If you haven't already contacted TAC and got this sorted a few things. 

1) You are running an extremely early version of 7.1 code, and we've got access to 7.1.13 already. You're currently missing security fixed for a handful of CVEs that really should be in place, you're missing a handful of updates specifically for memory issues, multiple updates for memory related issues specific to the PA-3020 series. I wold highly consider updating to a newer version of code, which is likely going to be one of the first things TAC recommends. 

2) Do you know what your normal utilization was to begin with?


I wouldn't really call what you are seeing a high memory utilization on a 3020 with the number of security policies and VPN tunnels that are in place. One of my active PA-3020s right now is running with the following, and I would call this a "normal" load for this time of the morning. If you are worried about this, then please run the 'show system resources' command and list the processes that are consuming the highest memory percentage so we can see if one of this is possibly misbehaving.
