1721 router hangs

I have a 1721 router with HWIC-4ESW as the external interface. The router NATs to the Internet and terminates 15 VPN's on this interface. Randomly the router will stop forwarding packets and on this interface which brings down the VPN's. No errors are logged on the console and the router is still available on the internal interface. A restart cures the problem for a short time. Also disabling and re-enabling the HWIC-4ESW also cures the problem. Any ideas appreciated. I suspect hardware fault but would also expect some error messages. Router has 96MB RAM and have tried various IOS images (currently running 12.4(12)
