i am facing this problem with vsphere cloud plugin , where i have configured my slaves (vsphere images) to be turned on on demand, the problem is when i submit the job it goes in waiting queue , after a while Jenkins turn on the corresponding slave , now while the process of turning on the slave is in progress a poll operation is performed by jenkins and restarts the slave , so this operation keeps on going endlessly.

Retention strategy polls after every two minutes and resets the slave , is there any way to increase this polling period ?
