      Using SSH based slaves, if you are running two or more agents on a slave, and have concurrent builds running, all of the jobs will unexpectedly fail due to SSH disconnections when one of them finishes. 

       Example of job that was running when another finished.

 Stage 'Deployment' skipped due to earlier failure(s)

      This is persistent and happens regularly.
      I've tried making two slave with one agent each (that point to the same physical slave) but the problem persists.

      This is an issue for us as builds take 3hrs on high powered machines and it's not feasible to run them one after another, we need parallel.
