GET VPN - Key Server Router Low Memory - Problems

Hi.

Currently customer is using Key Servers running with 12.4(15)T3 Advanced Security on Cisco 3725 routers.. They are supporting 8 Group Members. All Key Servers (3725) routers are working with 256MB RAM. They are only doing as key server and nothing more.

For some reason both routers were showing low memory problems and were unable to work properly. Even the console port wasn't responding. Below the only output I can get from the console port before powering off/on the router.

Anyone knows about an IOS problem/bug with that particular version? Because I think 256MB RAM is more than enough to support Key Server functions when only 8 Group Members are only active.

Please advise,

I couldn't find a bug match. Any one have any idea?
