Abstract: Various embodiments for a thread management system are described herein. An embodiment operates by determining that one or more scheduler threads of a server are allocated from a shared memory. A request to spawn a native thread at the server is received. The request is intercepted and an override for the request in which the resources for spawning the native thread are requested from the shared memory is executed. An allocation of resources for spawning and executing the native thread is received from the shared memory. An error on the server is detected. The shared memory is dumped into a dump file responsive to determining the error. The dump file includes an indication of what threads were allocated from the shared memory. The one or more scheduler threads and the native thread are restarted after the dumping.
