I have one project with two configurations - one per build machine/architecture. When I check in a change, only one configuration every builds. The second records the number of files changed, and remains in "pending" mode, even though it has two idle agents. I can manually trigger a successful build on either agent. Both configurations are set to build on VCS changes.
The configuration that is not building now was building just fine before I added the second configuration. Now only the second configuration is auto-building.
Can someone tell me why this may be happening?
