The th3mis commented on JENKINS-31050   Re: Slave goes offline during the build Hello everyone, I faced with same problem when slave goes offline during the build using SSH or JNLP agent. TLDR:  Process hierarchy of Jenkins agent and build shell with same PGID, so kill(pid = 0,  signal = SIGTERM) will crash Jenkins agent too.   PID PGID SID TPGID COMMAND 13691 13691 49864 13691 java -jar agent.jar 13818 13691 49864 13691 \_ /bin/sh -xe /tmp/jenkins4748921288996267614.sh 13820 13691 49864 13691 \_ kill(0, SIGTERM)   **I propose some agent demonization for except such bug  (call setsid() in thread pool?) Description: For our example we builds many project using make, so it build and abort build many times,GNU make has pid = 0 in internal structure, so when we click abort build on Jenkins it send SIGTERM to child processes -> make send SIGTERM to child and sometimes GNU make (fixed after ) calls `kill(0, SIGTERM)` which means on Linux agent that all the process group will be terminated included Jenkins agent -> so we get died agent during the build.
