Mr Cyberjock,
Your suggestions around products are solid choices and I'm sure they will help others around their design and needs.
Keep in mind the products I originally choose for my design fit my design goals, budget, and what I had on hand to use.
No they were not optimal, no they were not perfect, but they worked well for my needs.
Late November I updated some items - NICs, RAM, Mobo/CPU etc. based on some further design decisions.
I didn't update my signature till just now (see below).
Now getting back on topic this issue occurs for me under two different configurations and versions of FreeNAS and it sounds like it is happening to others.
By chance does anyone have a helpful suggestion that might help myself or others resolve this?
