Method to segregate suspicious threads in a hosted environment to prevent CPU resource exhaustion from hung threads

A system and method for segregating suspicious threads in a hosted environment to prevent CPU resource exhaustion from hung threads are disclosed. An application server identify suspicious threads that may cause the threads to hang or to execute for a long period of time and transfers the suspicious threads to a thread quarantine manager, where the suspicious threads are bundled together with other threads that have been identified to be hung or to be executed for a long period of time.
