SSL VPN Pool Exhausted Bug

in SSL VPN
On one of our NSA2650 units we upgraded from 6.5.4.5 to 6.5.4.9 about two weeks ago and now are getting an issue where the SSL VPN IP Pool exhausts and we have to increase it to allow users to connect. There are far more IPs in the pool than there are SSL VPN Licenses. It is almost as if the firewall is not expiring any of the leases to the clients that connect.
Has anyone else seen this behavior? Is this resolved in 6.5.4.10? I could find no mention of it in the release notes.

Some users have found that this was caused by user session timeout setting and that impacted the ssl-vpn engine where users were listed multiple times even after disconnecting from ssl-vpn. This might not even be a bug, but I do not know for sure.
