That's all understandable when speaking of errors and packet
loss, but would it really cause the CPU hit 100% at 50kpps?
both em0 and em1?
By the way, it worked for 3 weeks with regular load (about
10kpps) and the CPU was around 20%(each) and there were no errors.

10kpps - 20% CPU
50kpps - 100% CPU
looks like we have some logic here. I've looked at my graphs -
there is no relation between cpu load and pps. Do you have this
relation? Not talking about your extreme case 50kpps, generally - when
load fluctuates let's say 10 to 15kpps, does you cpu load also goes
higher/lower?
I experienced 100% CPU only in two cases:
1) Multicast went from LAN to WAN and caused storm (in carped
setup)
2) There is known bug with slbd.
