             Summary: STS implementation may lead to performance reduction
                 Key: RAMPART-423
                 URL: https://issues.apache.org/jira/browse/RAMPART-423
             Project: Rampart
          Issue Type: Bug
          Components: rampart-trust
    Affects Versions: 1.6.2
            Reporter: Boris Dushanov


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.
