Upon further investigation we get this error while debugging any application 
when there are multiple applications with the same process name running.  If we 
terminate the other processes with the same name the problem goes away.  It 
almost seems that the debugger is querying the O/S for the process name and 
takes the first one that matches which may not necessarily be the one we are 
debugging.
