Are you concerned about tmpreaper or cron jobs that periodically cleanup
/tmp? There may indeed be an issue for applications that run for weeks
or months. If someone is using jmap, jcmd or other tools using the
attach API then it will trigger the attach listener to start. When they
come back in a few weeks then the .java_pid<pid> file may have been
removed so they cannot attach. Is this what what you are pointing out?
