Hello Christ,
I've seen a similar occurence which apparently was caused by the
CSCdw58350 (although without the proper decode of the

Feel free to unicast me the case#, which contains more information on
the box that had sent this error message, then I can doublecheck this
assumption.
thanks,
andrew
