PLM periodically checks whether PSM is alive and healthy by sending IPI notifications to PSMFW. Both PLM and PSM firmware maintain counters and periodically make sure that they are in sync. If PSM is not alive and healthy, PLM throws the PSM keep alive error. The PLM can also notify you about the PSM keep alive error if you have registered for the PSM keep alive error.
