title: Jenkins slave went offline during build
body: <p>Jenkins slave going offline during build. How can I fix this , I saw lot of related questions in SO and Jenkins issues but no one gave solution.</p>
  
  <p>My configuration:</p>
  
  <p>Jenkins version 1.651.1,
  Zuul version 2.1.1.dev393 with one Jenkins master(Ubuntu),
  2 slaves(Ubuntu) each has 16GB of RAM 
  Running builds in parallel.</p>
  
  <p>Jenkins master, devstack and both nodepool slaves are in same IP range.</p>
  
  <p>I'm facing an issue when one of the slave completes its build then the java process in both the slaves is getting killed so the other slave going offline.</p>
  
  <p>I found this issue by listing out the processes running in the slaves and observed that java process is getting killed simultaneous in both slaves when one of the slave completed its build and the other slave is still running the build.</p>
  
  <p>Previously I had this issue and that was resolved by switching to Oracle's JDK from Open JDK. Now slaves are using oracle java 1.8.0_111 but now we getting same issue with Oracle-java8 also</p>
  
  <p>Build logs:</p>
