High CPU usage from /usr/local/bin/php-cgi -f /usr/local/sbin/
-
Recently /usr/local/bin/php-cgi -f /usr/local/sbin/ started eating CPU, rebooting the system has no effect.
2.3.4-RELEASE-p1 (amd64) on a Dell OptiPlex 780 with a Core 2 Duo 3.2GHz with powerd enabled, this system would run at 1600MHz (lowest speed), now it sits at 3.2GHz all the time.

The last two things I changed were enabling DDNS and OpenVPN, disabling those service has no effect.

Not useful, try
ps auxwwinstead.

Perhaps disable DHCPv6 altogether. Or you might delete /var/dhcpd/var/db/dhcpd6.leases and start over. (Copy it somewhere if you want to debug it.)

Thanks for the advice.
I turned off dhcp 6 server, moved the lease files, re-enabled. Issue came straight back. Tried the same again but with a reboot before re-enabling, issue came back.
Left dhcp 6 server disabled, but with Router Advertisements set to assisted (this was how it was previously set), IPv6 appears to work fine, and CPU usage is back to normal.
-
With DHCPv6 off, you can set RA to Unmanaged. (Doesn't matter much though.)
Other than that, the bunch of whacky expensive preg_match() calls in /usr/local/sbin/prefixes.php trying to parse the leases file is not something I'd be exactly interested in debugging/tuning, maybe someone else. Best to leave DHCPv6 off, not really needed for IPv6.

Awesome, thank you for helping solve this!
