You may just be hitting this:

I don't know much about any of the heap reporting beyond the numbers.

With respect to Nagios, what I did was to implement a mailer in logback that sent me a page if it logged an out of memory exception. Admittedly that's reactive, but I didn't have more memory to give it, so it either was going to stay up or not (and it did not, even Jim's G1 GC suggestion doesn't keep a 32-bit IdP up with a max heap now).
