I suspect this is an none issue now as everything is OK. My best guess 
is that the RAID array was rebuilding itself as there were a few mpt cam 
events logged overnight and the problem seems to have gone away after that.

Now I'm left with one problem which is a bit different so I'll start it 
on its own topic
Cheers for the help folks.
