Die on unhandled exceptions
This option suppresses any windows that may pop up as a result of a process
failing, which hopefully facilitates the full completion of the process and the
release of committed resources after a process fails.
This should be used on systems that have other management mechanisms in
place to alert an administrator that a process has terminated abnormally.
Silent breakaway
This causes any process started by the executing process group to execute
outside of the process group. This implies that the newly created process will
not be subject to the Process Control rules of the parent process. It is,
however, now a candidate for Process Control, according to the master list of
Process Control rules, and will be subject to the rules on the next
management sweep.
By default, Process Control checks once a minute for processes that fit the
rules. This parameter is called Process Scan Interval, and is configured from
the Process Control Properties window (right-click Process Control (Local)
in Figure 5-25 on page 156 and click Properties then click the Service tab).
