Two days ago I upgraded packetfence 4.7.0 to 5.5.2
Applied all the upgrade procedure steps in the packetfence upgrade guide.
1. The CPU load is very high at 70%-100%.
I ran 'top' and pfqueue was responsible for the CPUload.
In the admin interface there is a menu item PFQueue. The lists one metric:
pfdhcplistener, and the count column is showing values between 5K and 8K.
and the error in logs/pfqueue.log
