I found this discussion along the way during my discovery - https://lists.buildbot.net/pipermail/devel/2006-October/001555.html Hence this is what could happen, i gave up on permanent solution and resolve on my own workaround. $ buildbot restart yocto-controller never saw process go away $ ps -ef | grep twistd user 6577 1522 1 10:19 ? 00:00:07 /usr/bin/python3 -c from twisted.scripts import twistd; twistd.run() --no_save --logfile=twistd.log --python=buildbot.tac user 7536 4318 0 10:28 pts/2 00:00:00 grep --color=auto twistd $ twistd-kill ~/yocto-controller restart # Simple script to forcefully killed the reactor still running on the background. #!/usr/bin -xe BUILDBOT_PATH=$1 BUILDBOT_ACTION = $2 kill -9 `cat $BUILDBOT_PATH/twistd.pid` buildbot $BUILDBOT_ACTION $BUILDBOT_PATH 81001 1 aaron.chun.yew.chan 2018-07-03 01:59:01 +0000 This ticket is no longer needed as the issue is not with Yocto Projet but rather this threat should posted with devel-Buildbot community. 81002 2 aaron.chun.yew.chan 2018-07-03 02:01:03 +0000 Resolve this ticket since its not a bug. Its basically to hightlight the issues observed when we moved from old Buildbot 0.8.8 into newer version Buildbot 1.1.+
