Problem starting the Report server

Hi,                                                                     
                                                                        
Hope you shed some light on this. I tried to stop & start the reporting server and the stopping & starting processes  without any issue with the commands below:                               
                                                                        
./stopServer.sh RationalReportingServer -profileName                    
RationalReportingSvr -username abcdmin -password abcxxxx                
                                                                        
./startServer.sh RationalReportingServer -profileName                   
RationalReportingSvr                                                    
                                                                       
But I have problem to access the reporting server after a restart (even
wait for 20 minutes) via  "http://InsightServer:9081/reporting", then I
need to reboot the reporting server in order to gain access again.      
                                                                        
I have noticed every time after a stopserver and startserver and found the following       
process is missing or failed to start which could be the reason that I  
can not access the reporting server.                                    
                                      
Here's the missing process:
