I've got many nodes running on different Linux distribution and also few windows nodes running with SSH slaves and Cygwin (https://wiki.jenkins-ci.org/display/JENKINS/SSH+slaves+and+Cygwin)

Using the following pipeline script:

_node('linuxHost') {
stage('linuxHost linux')

{ sh '''sleep 30''' }

}
node('windowsHost') {
stage('windowsHost cygwin')

{ bat 'sleep 30' sh '''sleep 30''' }

}_

On my windows node I always got an error "ERROR: script returned exit code -1" if my script execution time is greater than about 250ms no matter what the command content is (that's why I'm using a basic sleep for this example). I've got the exact same behavior for all of my windows nodes.

Here are the execution logs:

May be related to JENKINS-32017 ?
It works fine using the same node and the "Execute Shell" build step in a freestyle project.
