Do you still have the data that caused this crash? Will it continue to 
re-occur each time you restart a down server? (Can you continue to reproduce 
the event...)

Please print *op and *eip as well. Also, what's in frame 4 or higher, what 
function called hdb_cache_find_ndn(), does the stack trace stop there or is 
there more?
