Frequent high CPU load on APU board [IPv6]
-
Hi,
I'm using pfSense 2.1.5 on an APU board. I recently configured native IPv6, and I noticed some strange CPU load since then:
The load "survives" a reboot (the load continues even after a reload, we can see that at the right of the picture), and I could see the load is due to a "php" and "check_reload_status" processes.
I did not have that problem before configuring IPv6, nor with my previous firewall, an Alix board with IPv6 through the SixXS tunnel broker.
Any idea what could be the problem? I installed a pristine pfSense on this board, and kept all defaults, except for the ftp proxy handler, which I disabled.

If check_reload_status is using high CPU, that is a symptom of another cause. Usually it's that a gateway is being flagged as down/up, or an interface is bouncing somehow.
I've also seen that in one case where it as a dodgy DHCPv6 server at the ISP on their WAN, disabling DHCPv6 on WAN settled it down.
