Hi Joseph,
We have a known issue with relation to using 256-bit encryption. If this is the case, you can download the hotfix for this at the following location:

If not, would you be able to provide some data, screenshots, logs, etc... showing this leak? Are you saying that it uses a lot of memory or that it's actually leaking memory? If it's leaking, I'd like to see how you're determining that so we can go back an retest on our end.
Thanks.
