Thanks. But is there a dedicated thread to monitor this? If using socket monitoring, how when the app crashes, in this case there would be no socket close, thus how this can be detected?

This is generated based on the socket connectivity with the application/component process. So, upon process death/exit you are seeing this event being generated for all processing using OpenSAF agent libraries. (Ofcourse, you could attach the process to strace or debug the coredump of your application to understand where the crash or exit happened!)
