1721 router-interface "blocking"

Central and branch office LANs are conected over Frame Relay. After few hours of proper work, one router (1721,Branch Office) lost his interfaces;LED indicators for both WIC are on (but there is only one WIC card inserted, serial interface cannot be pinged from outside), LED for Ethernet is off(interface cannot be pinged from inside). Console port is also unavailable.

Few hours later (the router is unpluged), after restarting it works properly for some time...

Thanks

Ivana
