It should probably say "Replay cache I/O operation failed", and give  
some more detail.  Unfortunately, there are several places where some  
kind of failing operation on the replay cache gets mapped into this  
one internal error code.  My first guess would be that a replay cache  
might have been left around under a different uid; it's expected that  
all services sharing a given principal will operate under the same  
uid, since they all need access to the same service principal key.
