When you start the probe wasp the probe don't get the ip address and the port number

Open the wasp.cfg change load_on_startup = true to load_on_startup = false except for root and usm
and make sure the probe start and get ip address and port, if gets, you have some portlet with an issue.
Based on the last line for the portal log maybe will be a issue with the portlet that the portal show on the last line.
On this case jasperserver-pro was the issue.
After you disabled all start one by one to check with one is causing the issue.
