You should have a look what these slow queries are. With bad luck, one
bad query can queue up all others after it.

If that is the RH delivered binary (and to me it looks so), you may
want consider to use a pre-compiled binary from MySQL's website. There
are known issues with RH compiler and MySQL (and pre-compiled)
binaries - although I am not sure whether thy apply to your
environment. Btw, I doubt that this would be the source of your load
problems - I mentioned it just for completeness.
Bye,
