Broken Links?

Hi,
I have a deployed app and when looking at the webserver statistics I find a 
number of not found which look like this:

/cgi-bin/WebObjects/myapp.woa/2/wo/dKExjTwyEi92ir6nz2dheM/0.8.4.0.2.4.1.0.1.0.6.1.0.0.0.0.2.0.1.0.1.4.0

There is no referrer given in the statistics. Where do these come from? Is 
the App/Server load too great so the links are not served correctly? They 
cannot mean broken links as there would be either a error or null returned 
when a link is not found?

Thanks for some input.

Regards

Ute
