James Peach created MESOS-8166: ---------------------------------- Summary: Improve reaper responsiveness on Linux Key: MESOS-8166 URL: https://issues.apache.org/jira/browse/MESOS-8166 Project: Mesos Issue Type: Bug Reporter: James Peach
The {{ReaperProcess}} polls at a dynamic interval to determine whether any of its monitored PIDs have exited. In the common case of a child process exiting, we should be able to improve its responsiveness by using [signalfd|http://man7.org/linux/man-pages/man2/signalfd.2.html] to catch {{SIGCHLD}} and immediately reap any exited processes. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
