High CPU after 2.1.0p11/13 upgrade from 2.0.0p23

After we’ve adjusted the SNMP backend from inline to classic for APC ups devices we also see the CPU usage gets back to normal again.

We’re running multiple CheckMK virtual appliances (1.60) and ChecMK 2.1 (2.1.0p18).

Thanks for sharing this workaround.
