Root Cause: WPs and CPs are started in the sequence of their names.
When starting a process from the System Overview or the Administration perspective, the lowest available combination of WP name/port from ucsrv.ini is used by default.
There is no method provided to start the process 'WPx' explicitly.
When starting a process in the AWI or the UI, the Service Name is sent to the Service Manager (SMgr).
The SMgr tries to start this service, and reports back if it is already running. There is however, no correlation between the service name and the process name.
Fix Status: No Fix
Use the Service Manager [Dialog] to start the WP.
