For 2) from the description, I'm attaching a patch that optimizes the work of the STS by reducing the number of iterations.

> Recently we come up to a case in which a system was declining in response time when working for a few hours. In the end the system stops responding.
> It turned out that two tokens are inserted in the STS per second.Because of :
> 1) the lack of retention policy of the store i.e. the EXPIRED tokens are not cleaned up and are constantly iterated(RAMPART-337)
> 2) the number of iterations, which could actually be reduced
> the system may either stop responding or throws OOM exception.
