The debug mode I am using is 0, which is set in the .cfg file.

I am using solaris. The default mode is synchronous, and actually I don't
think solaris support asynchronous write.
openser use syslog to log in debugging information, right? If the mode
matters, can I just simply disable openser from logging in any information
to files?

thanks,
