We're running Jenkins ver. 1.617

I setup a Jenkins Slave Service on several Windows machines.

I noticed that the Service on Windows keeps stopping and restarting again (see log below).

Sometimes it stops and never restarts by itself,

as a result, it is disconnected from Jenkins master.

Is there a reason for that?

How can I detect what's causing this?

Does upgrading to Jenkins 2 solve the problem?

Here's few lines from the log:
