I can, but my bosses will kick my ass if I bring down the ISP again :)

If you think it's the only way to find the problem I'll tell them that
I need to do it. In this case, please tell me what other config
options/tools I can use to get as much info as possible...since I'll
probably be able to test this only once more on the production
environment for debugging purposes.

Cheers,

Felipe Damasio
