I feel almost silly for asking this, since it seems some basic, but I haven't found a good way to prevent this from happening. I have two build agents and our builds are set to trigger from changes in VCS (90s quiet time). How do I prevent the 2nd build agent from kicking off a build which is already started by the 1st build agent a few minutes earlier? I've looked at the different build triggers and couldn't find anything which would prevent this scenario?
PS. I'm using the latest 3.1 EAP (6692) if it matters.
