| When a job running on a remote node "fails" because the connection drops, it should be possible to restart it automatically. Currently it's cumbersome to get a list of the failed children jobs and checking how they failed by grepping for java.io.EOFException in their log files. https://groups.google.com/forum/#!topic/jenkinsci-users/sjnF6zlPd3Q This is how the failure looks in the children job console output:
Building remotely on instance-1 (tag1) in workspace /var/lib/jenkins/workspace/eval
[vmu-eval-single] $ /bin/sh -xe /tmp/jenkins4616924287086740166.sh
+ /path/to/evaluation-tool
