Barnyard2 not writing to its log directory

[jrmain]

I'm using the '-l' argument to tell barnyard2 where to write its own log. However, I never see any files being created or updated there. Documentation on barnyard's logging seems a bit sparse. What exactly is it supposed to write to its log?

I'm asking about this because barnyard2 has been crashing recently (database errors), and it would be nice to see relevant information in a log. Instead of that, I have to run barnyard2 from the command line and wait for it to crash again.

This is on Windows 8.1 64 bit.
