You said I still have 100+ processes open....I guess you mean threads(a.k.a LWPs on Linux)
Generally if a amscore does not have nay pending connections it dies off on its own...However number of threads i.e LWPs won't die down, since they are actually threads of an active process.
One way to shutdown amscore peridoically is to set appropriate RollOver and MaxCore values inside LifeTime Tag of Application.xml...However note that when ever a core rolls any active connections on it will be terminated...Thus Rollover period should be larger that largest possible connection/playback duration in order to prevent any surprise to any end user.
Yes, I meant threads! :-) Thanks for the hints
