How to troubleshoot High load average values on a new 2.1 NanoBSD VGA install?
-
I noticed higher power consumption (19 Watts) instead of the "usual" 15 Watts. After viewing the pfSense Status: Dashboard, I noticed that the load average values are not the usual 0.00 0.01 0.00 but "0.80, 0.80, 0.77" instead. This was at approximately 6 hours of uptime.
The "pfSense High load troubleshooting documentation" does help me a little.
