What is this TPS IPC process?  Why such a high CPU utilization?

TPS in ‘TPS IPC Process’ stands for ‘Trust Point Security’. This process works very closely with SMD Session manager daemon. Together these do help service the authentication and session management routines. It's related to AAA services.
