      I have a Netgate 3100 pfsense box that has been giving me trouble with intermittent packet loss. I know its this box because I've bypassed my firewall and went direct to the cable modem. The diagnostics System Activity section is showing me very high wcpu and I am trying to find out if that is the culprit. The CPU display on the main page looks fine though. I've also noticed the idle time is really low and I didnt think that looked right. I've ran some commands I found on the internet but having some trouble deciphering what to do next. I am thinking of doing a reset on the device but I was hoping to learn a little more of how to find what is causing the wcpu be pegged like that, if that is the issue. I really dont run a bunch of packages on this unit as well.

        Nothing shown there is unexpected. The idle processes shown as using high CPU are normal. That's what shows as using CPU cycles when nothing else requires them.

        I assume it was not dropping packets at that time?

        You should not run Kea on the 3100. There are known upstream bugs in arm32 that affect it. That wouldn't cause packet loss though.

        You should upgrade. 24.03 is now a very old release.

          @stephenw10 Thank you. Updating the firewall fixed it. I'm embarrassed it was so far behind. Opendns was blocking it from showing an update was available and in addition it was reporting to me I was on the latest. Thanks for looking at my post!
