I concur. Snort is a great program, but the false positives are many.
What are the errors that it is tripping? Many people have to
custom-tailor their snort rules (by disabling problem rules) to allow
legitimate traffic.

One thing that helps me is I have snort emerged with 'USE="flexresp
inline"', and then used oinkmaster to convert all my tcp alert rules to
drop. It helps a little in diagnosing false positives.
