Dhcpd does not run on LAGG0 interface

[fnords]

I use dhcpd on LAGG0 interface, using LACP -
the server won't bind

Not sure where you're getting the output from; lsof isn't installed on pfSense, and the output you're showing can't be grepped with 67 since it is resolving services to names.

Use netstat -an | grep 67

Fact is, dhcpd does not work on LAGG0
I can't explain why if you need further logfiles feel free to ask

WTH is this lsof nonsense over and over again? And ps auxw? This is not how you check things, as already said above. Also, you have 6 instances of DHCPd running, a bit too much if you ask me.
