[GE users] Frontend as exec host

Ladies and Gentlemen,

I am trying to add the frontend as an execution host but I am having some weird problems. I added as many suggested on the web, i.e., running ./exec_host at the frontend and accepting all questions. Everything looked fine, as below. The cluster.local was added, I see the load, slots available, etc...

But  as soon as I add jobs to fill up the entire cluster, problems appear. First, no jobs start to run on the frontend. Second, the load_avg changes to -NA-.

Any clue on how to fix it?

Thanks!

Demetrio
