Sandboxed execution of plug-ins
A sandbox architecture that isolates and identifies misbehaving plug-ins (intentional or unintentional) to prevent system interruptions and failure. Based on plug-in errors, the architecture automatically disables and blocks registration of the bad plug-in via a penalty point system.
