The UMP wasp was restarted due to some issues with unresponsiveness.
The probe would not restart, so it was deactivated and reactivated.
The probe never fully restarted (meaning it never gets a port assignment)
Followed instructions in
KB000007118 : WASP module don't start
and configured all portlets except usm and ROOT to not start automatically, but the wasp probe still does not start.
No errors are reported in either the portal.log or wasp,.log during the probe startup.
The last lines recorded in the wasp.log file at loglevel 5 are:
INFO [localhost-startStop-1, org.apache.catalina.core.ContainerBase.[wasp-engine].[localhost].[/]] Initializing Spring root WebApplicationContext
INFO [localhost-startStop-1, org.apache.catalina.core.ContainerBase.[wasp-engine].[localhost].[/]] Initializing Spring FrameworkServlet 'Remoting Servlet'
