          francisu it still happens with v 1.36
          The gradle build stops in between with "Agent went offline during the build" and with the error above. That error is too generic, I am not able to figure what's the root cause of it.

          and I verified its nothing with that particular build job, the ec2 slave just looses the ssh connection after around 10 minutes.

          Was this ever solved deepanshu11madan? I'm having the same issue. I think it is something to do with the OS
