Drobo & Droboshare drop offline after afew minutes

I have a 2nd geneation drobo with droboshare. After a few minutes (more than 15, less than an hour) the shares are suddenly inaccessible. OS is Windows 7, firmware is 1.12 droboshare is 3.51.

Please don’t say Windows 7 is deveopment, it’s already been released to MSDN and Technet subscribers.

Reading through the forum seems to reveal this as a common complaint.

Does anyone have a fix?

I’ve started to document the problem here:
and has been mentioned before:

No word from Data Robotics on this very serious issue.
Personally i’d rather go back to a previous firmware but it’s not available.
