statmonitor -X started from STN_STATMONITOR_ARGS does not stop when Stone stops
The statmonitor -X argument runs a startmonitor that collects host statistics only, and does not attach to a Stone.
When statmonitor -X is started during Stone startup by including it in the argument to STN_STATMONITOR_ARGS or similar configuration parameters, the statmonitor was launched, but would of course not naturally stop when the Stone was stopped.
Workaround
Do not use -X in the arguments to STN_STATMONITOR_ARGS; you must manually track down and kill statmonitor processes started in this way.
In 3.5.3 and later, -X is disallowed in STN_STATMONITOR_ARGS.
