[c-nsp] Anyone running s3223-advipservicesk9_wan-mz.122-33.SXI4a?

[Jens S Andersen]

Hi Peter

The router is doing layer2 and 3. (OSPF, HSRP, PVST)
The router is totally unresponsive, even after the loop is broken (by shutting
an interface on the neighbour-router). 
Power off helps.....

Logging on to the other routers is difficult/impossible because they are
overloaded. Would a scheuler allocate make any difference here?

All I can see in the logfiles is host/address-flapping and storm-control kicking
in.
