Abstract
A method and a system for request routing may include a router configured to forward a request to a process. The process may acquire a lock on a memory object. If the process is becomes hung, a data synchronizer may release the lock on the memory object assigned to the process. The lock on the memory object assigned to the process may be released after the process is detected to be hung and after another process requests a lock to the memory object. The router may list inactive processes, and if the process is hung, add the process to the list of inactive processes. The router may be configured to check the inactive list and not route requests to processes on the inactive list. The data synchronizer may be configured to prevent processes on the inactive list from modifying data.
