      I've had a KillStuckPolling.groovy job running for about 6 months without problems, but on January 4th it stopped working with the below stack trace. This matches with the release of Jenkins 1.446, which is currently installed. I have tried to restart the server without any effect.

      The groovy script is as follows:

      KillStuckPolling.groovy
       Thread.getAllStackTraces().keySet().each() { 
   item ->
   println "Checking item" + item.getName();
   if (item.getName().contains("SCM polling") && item.getName().contains("waiting for hudson.remoting")) { 
     println "   Interrupting thread " + item.getId(); 
     item.interrupt() 
   }
 }

      And the bash script used to start it is as follows

      KillStuckPolling.sh
      #!/bin/bash -e
echo "## Kills stuck polling jobs on Jenkins"

if [ -z "$JENKINS_URL" ]; then
  echo "ERROR: This script must be run on Jenkins. It cannot be run manually"
  exit 1
fi

echo "Getting latest Jenkins CLI from ${JENKINS_URL}"
if [ -w jenkins-cli.jar ]; then
  rm jenkins-cli.jar
fi
wget ${JENKINS_URL}jnlpJars/jenkins-cli.jar
echo "Killing all stuck SCM polls using ~/bin/KillStuckPolling.groovy"
java -jar jenkins-cli.jar -s ${JENKINS_URL}/ groovy ~/bin/KillStuckPolling.groovy
