[j-nsp] Odd behaviour testing failover

[Jared Gull]

Gordon,

I haven't done much GRES testing in the 7.3 release
but prior to that I have and have seen no such
behavior.  Have you been able to reproduce this or was
it only seen one time?  If this happened only once I
would say that HDD does sound suspect.
