It was probably a large packet flood to random destination ports. Some of them happened to hit rshell. What really took out your routing procs was likely a huge packet flood, but due to volume you may not have been able to access normal interface counters (i.e. MRTG doesn't get any SNMP packets back when OSPF goes bye-bye).
