Hi all,

one question, is it possible to prevent the parallel execution of a certain configuration when it is already running.

E.g. we have multiple agents available, configuration A ist started (by Trigger or manually) and someone starts the same configuration (again by Trigger or manually). We want to prevent that the second build is started on the other available agent until the first one has finished.

I hope i described this well enough :)

Thanks

Holger

Have look at Shared Resources - [http://wiki.finalbuilder.com/displa...+Resources](http://wiki.finalbuilder.com/display/continua/Shared+Resources) - your Stage can take a lock on a shared resource to block other builds from starting until they can lock on the resource.
