Title: IPv6 on PPPoE eats 100% of CPU
Post by: luzemario on March 26, 2018, 04:17:20 AM

Hi guys,

The phyton 2.7 process is using 100% of CPU and is dying often. The command below is the source of the problem. My WAN is using PPPoE on IPv4. I don't know if is possible to have PPPoE on IPv6. Maybe this can be the cause of the issue?

I did not configure IPv6 on this interface for PPPoE, only IPv4 has PPPoE on the WAN interface. Toughts?

Code Select

/usr/local/bin/python2.7 /usr/local/opnsense/service/configd_ctl.py interface newipv6 ppp

PPPoE is single threaded and will eat up a lot of CPU if the traffic is intense and the CPU is not powerful enough...

You can disable (set it to "disabled") IPv6 entirely on the WAN.
