Running TG 2.0.3 on Ubuntu 9.x with Python 2.6 and getting this
following error message in my paster output log periodically. Nothing
else before or after is displaying as anomalous. Thoughts?

Looks like a malformed HTTP-request to me. We have a sanitize-middleware
hooked into our app that cleans these out.

Thanks; and thanks for your previous help to my migration inquiries. I think my new TG2 app is purring away and stable. I'll definitely be writing up some recipes out of this experience to post.

I guess my question is that I'm wondering if this kind of thing cause paster/pylons to hang threads, leak memory, etc. I'm looking for a cause right now of a problem where I have a very stable system for a long time and then see CPU percentage steadily creep up and hold until that instance becomes extremely slow or non-responsive... and I don't see necessarily a correlation with memory creep so, it doesn't look like a classic memory leak; more like hung/stuck code. More research required for sure.
