Odd apache error

[keegan]

Well, i wrote a parser for my logs in apache, and this error has occured over 3000 times in the past 2 weeks: No directory () for Hostname www.thekeegster.com does anyone know what this means? I've been googling, but i haven't found anything. Its clogging up my errorlog, its amazing how many occurences there are of it. I'm runnin apache 1.3 on Linux *.* cin >> knowledge;
