Answer 1

I was experiencing a similar error as the OP where the connection to my slave was dropping. The root cause of the issue was not due to a mismatch in Java versions between Jenkins slave and master hosts.

Solution If you are running Jenkins in an EC2 instance on AWS behind an Elastic Load Balancer (ELB), increase the "idle timeout" value under the "attributes" section from the default 60 seconds. I set the new value to 600 and no longer experienced the error.

It appears that if a single command in your build process takes greater than 60 seconds with no log output, the ELB will terminate the session due to idle activity.
