Job fails with [An existing connection was forcibly closed by the remote host]

Our Windows slaves are JNLP connected using scheduled tasks (like this: https://wiki.jenkins-ci.org/display/JENKINS/Launch+Java+Web+Start+slave+agent+via+Windows+Scheduler).

When a job starts working with a slave it suddenly fails because the connection was lost. It says something on slave side killed the connection. Few minutes afterwards the slave is back on-line. I am sure it is not a network issue as I tried pinging the network from system start-up till the problem occurs. I could not find find what kills the connection and disable TCP chimney (advice from google) did not work.

The exception is below.

I think proper behaviour would be not to fail the job but attempt to reconnect. Any hints of additional configuration that will help me resolve this issue is appreciated.
