You need to know if an application is still alive and working. If one or more application processes dies, pmfd will try to restart it automatically for you. > in the solaris ha cluster, I found rpc.pmfd thread, > we have a door machanism why we need rpc.pmfd? RPC is Remote Procedure Call. It's the mechanism that allows the cluster daemons to talk to each other and to other nodes.
