Hi, For our nightly testing, we revert slaves to a VMware snapshot before starting jobs.
Most of the time this works, but sometimes the first job after the revert job fails. The weird part is that a downstream job that runs on the same slave will often succeed less than two minutes after the upstream failure. I'm guessing that Jenkins thinks the slave is still online and rejecting the connection and/or not connecting. My idea for a work-around is to add a "snooze" time after the revert. This way, Jenkins can figure out that the slave is offline. So, what amount of time is necessary for Jenkins to realize that a slave is offline? 5, 10, ?? minutes? Note that for non-windows slaves, I'm not disconnecting the slave prior to revert. I had a "good reason" for doing this at the time, but can not remember it. Below are some snippets of console output showing my situation.
