Component: Dollar Universe
Cause type: By design
Root Cause: The error "error getting port number for [SIO]/[AREA]" appears in universe.log in case a command line like "uxlst atm AREA" is launched against an area that is not enabled in the node.
These errors are normal and can be ignored as they are certainly generated by the Uproc script that performs the online backup in the Dollar Universe 6 maintenance session.
This supervision or Uproc script can be fixed as there is probably a "uxlst atm AREA" command that is being launched against some areas that are not Enabled in this node, by forcing to only attempt to connect to the areas enabled on the node, these errors can be avoided.
