Memory Leak since 22.01 Upgrade
-
Hello,
Since we upgraded our pfSense to 22.01 I have noticed that after about 2 weeks Memory will slowly creep up from ~30% to max'd out before it starts logging swap related errors in the system logs. We then need to reboot and it is good for another 2 weeks before this happens again.
This is only a T2 Nano however we have not had this issue before and configuration/usage remains the same. We have other pfSense devices in AWS that do not have this issue. The primary difference is that this is the only one running IPSEC. I have confirmed that I do not see the pcsd process running as described in here. And we only have a few packages installed.
Below is a "top -aSH -o res -w". Can anyone advise if it is expected to see so many ipsec processes running at the same time? Or is there anything else of concern?

Maybe its correlated to this:

@fireodo
OK, thanks for that information. I'll take and look and see if its mentioned as a fix in the release notes for 22.05. -
@ironmonkey If it is in the system patches already then it's likely in the 22.05 builds.
I haven't gone looking for this specific issue, though, so YMMV.

Hi @rcoleman-netgate
Is there a way I can search the system patches to see if it's included in 22.05?Thanks.

@ironmonkey If the Redmine catalog indicates something is included in 22.05 then it would be in the next release.
