5 years ago Well, POX carp is several years out of date, so the first thing I'd suggest is upgrading and seeing if that helps.
https://noxrepo.github.io/pox-doc/html/#getting-the-code-installing-pox has some notes on versions, etc. The latest version in the main repo is eel. You can also try the upcoming fangtooth branch from my fork: https://github.com/MurphyMc/pox

Hi,
I'm trying to run POX with misc.ip_loadbalancer, but I always get the following exception. Any hints on how to solve this?
Thanks a lot!
