The webapplication runs on 64 bit linux. The 3GB memory are needed to run about
300 parallel sessions with about 1000 request per minute, where as 10% are pdf
requests and the rest http.

We already limit the maximum number of parallel fop requests by using a pool of
3 pfdTransformer objects.

We blame fop 0.95 to be problem cause because the application runs without
problems when turning of the pdf requests or when using old fop 0.20.5 for pdf

I just started some investigations with profiler - it looks like a few kb
(~2kB) of memory get lost per pdf. I hope the attached screenshot helps to find
the potential problem cause.
