Problems with MySQL

I would like to know if somebody can help me with the following:
I'm using ASP with chilisoft in order to use it with mysql. I have a kind of
page that allows to update notes and display them in an asp page.
The problem is that I need to restart the ASP server when some errors ocurr such as
illegal assignment and then one parameter that corresponds to the connection to the DB.

I dont want to restart it, however, somebody told me is better if I restart
the server once per day. Thus, why do I need to restart the ASP server and why,
sometimes, after restart it, the problem still continue.

Whoever told you you should have to restart a server once a day is on crack. Why don't you just run ASP and mysql on a Windows box? Or run apache and develop in PHP -- this doesn't sound like a major application, so a port should be easy. Also look up asp2php (or is it asptophp?), which will supposedly port your code over for you.
