FileMaker Web Server Connector FMWSC error log

Is there a guide somewhere out there to the messages that I see in my FileMaker Web Server Connector (FMWSC) log file? (I have searched the forum and FileMaker's site and came up empty-handed.)

For instance, I would really like to know what is going on when I see messages such as:
