As the debug output from the server already suggested, the problem  
seems to be in the driver. The difference between running in normal  
and debug mode is that it won't background and won't write a PID file  
in debug mode. This is unexpected. Since backgrounding doesn't seem to  
be a problem, could you check if the PID file is there? And the  
config.log would be helpful, to see what is available on your system.
