From my searches through the web I have seen that the three services, Storage Profile Service, vSphere Web Client and Orchestrator all try to start on port 31000 by default. 
If your vCenter Service Health looks similar to this and has these three alerts you are probably running into this during startup.
License Services -
- Asset Properties History service - Cannot obtain asset properties from vCenter Server query service
- VMware vSphere Profile-driven Storage Service - Unable to retrieve health data from http://localhost/sps/health.xml
- VMware vCenter Storage Monitoring Service - Service initialization failed
This is a known issue with vCenter 5.0 U3
