I have a QuickBuild configuration that allows to run many test cases based on the inputs, and one test case runs on one node at a time. The node/system is reverted after each test. I have a trigger to send a large number of test cases to the configuration, and they are waiting until the nodes to be available. I am having two issues as follows:
 - QuickBuild server drops all of my test when all of the nodes in the resource disappeared.
 - The nodes/test systems are down (while reverting) but they are still showed as active on QB server. I am thinking of increasing heartbeat frequency at nodes' level. Is it possible?
 Any advice appreciated.
