I see per day many of these errors and I cannot find what they mean nor can I find what to do about it. Does somebody have an answer?

Hmm, this is strange, the URL looks OK.

Do you have the pdb file for the http module? We can put that up temporarily in debug mode so we can see the exact line to determine the issue.

Did this used to occur in previous releases? How many a day are we talking about? (in relation to traffic)

It looks like the url rewriter is trying to parse something to an int, when it's not actually an integer. There is no real way in .NET 1.1 to check for integers except maybe a regex (this is before parsing it). So I assume this may throw an error in your log if you hit the following url?

Maybe the code needs some preventative checks, I think .NET 2 has a tryparse. Can you log this at support.dotnetnuke.com ?

I logged this under http://support.dotnetnuke.com/issue/ViewIssue.aspx?id=2398. Maybe it is time for me to move to DNN 4.02 with .Net 2.0?
