Hi,
    Having run tracer after a system update how do I determine what it is referring to with the following messages:

You should restart:
* These applications manually:
     DiscoverNotifier
     Isolated Web Co
     Privileged Cont
     RDD Process
     Socket Process
     Utility Process
     Web Content
     WebExtensions


Additionally, there are:
 - 1 processes requiring restart of your session (i.e. Logging out & Logging in again)

regards,
Steve
