A socket got stuck in the FIN_WAIT_1 state coz the client that was generating these TCP segments got terminated prematurely. The kernel does clean it up after 2MSL seconds. However, I would like to know if there is a way to explicitly clean it up from the command line (as root). SO_REUSEADDR option only helps for sockets in TIME_WAIT. Also, Does the kernel have such mechanisms to clean up any kernel data structure? I would appreciate it if whoever answers this query also Cc me coz I'm not subscribed to the kernel mailing list.
