Managing the - Actions - database

I have inherited a fairly seasoned Satellite environment which runs rather well.

Lately I have been doing some regression testing and validation and attempting to use the output under Schedule | Actions.

Unfortunately I do not believe that anyone has ever archived (nor deleted) a single event in the history of the server and the number of events are over 100,000 !  When I try to "Select All" my Satellite appears to hang and then I get a JVM core.

Does anyone know of a way to use the API to manage the events?  Namely to archive then delete these events.

Thanks in advance for any advice!
