AFAIK, the use of multiple bridge interfaces shouldn't cause any issues
for perfdhcp. From this blog I don't exactly know what the problem could
have been. The error message is cryptic but it doesn't seem to be
related to the fact that the "eth1" interface wasn't not supported.

I was recently using the perfdhcp on CentOS and didn't observe those issues.

Please note that the latest version of perfdhcp is available with the
Kea DHCP server 0.9.1-beta version, released on February 18th. I
recommend to use this version. The versions shipped with BIND10 is old
and there have been some improvements and fixes since then.

I don't see why this wouldn't work. It would be best if you could try
running perfdhcp in your environment and in case you find any issues let
us know and we can work together to reproduce the problem.
