[SOLVED] New build CPU usage constantly at 25%?

[Solaris17]

Updated today and now running

OPNsense 15.7_1018-amd64   
FreeBSD 10.2-RELEASE-p1   
LibreSSL 2.2.3

however after the initial and subsequent (2) reboots of the router the CPU usage is sitting at 25% the router itself is running an i3-4130 but it is running warm now with the constant usage. Unfortunetely I am unable to find the process doing it?

The cores show the usage but the processes dont represent the missing %?

[AdSchellevis]

can you try to run top with a bit more info?

Code: [Select]

top -S -P

It's probably system or interrupt time being spend, if your machine is busy with network traffic that could be normal, if it's not routing/firewalling anything that looks odd.

yeah currently no one is home im pulling no bandwidth. before this would generally indicate a very low CPU usage .4 .3 etc on the avg load graph. but im talking consistently at 25% the read out via putty is

Do you see anything? If the system is constantly under load thats w/e I can understand if their is overhead or something. What is blowing my mind is that the 25% atleast to me isnt represented in the CPU usage stats. the cores themselves show idle states on ly in the 60's and mid 70's However the actual task list doesnt show me what is loading the system. Maybe im missing something simple since im not  used to tops print outs but thats atleast what it appears like to me?

[AdSchellevis]

idlepoll seems to be using 25% of your system, is your machine running in polling mode?
(System -> Networking -> Device polling)

That was it! Sorry I guess it didn't click for me on the list. I just thought it was some BSD specific watchdog I guess. Still haven't figured out how I managed to check that box. Thanks a ton! CPU is running much cooler! (these embedded heatsinks are not fantastic. and the thermal paste is terrible too even after re-apply)
