iPhoto library drops out

Hi I am a new Drobo FS customer, trying to get it to work consistently so I can forget about it, alas this is proving not to be the case.

I have been using Drobo support which can be a bit slow with UK-USA time differences, so I though I’d try this forum.

My problem is that I have placed mine and my wife’s separate iPhoto libraries onto the Drobo FS but and directed each iPhoto to each of the libraries, but they keep dropping connection and iPhoto needs to be reset.

Time machine however doesn’t have the same problem.
