Unable to save diagnostics, DDService.exe crash

Hi, new DroboPro user here.

I just fired up my new DroboPro with no drives, updated the firmware, then added 8 x 2TB Hitachi UltraStar A7K2000 drives.

One of the drives (slot 2) went red and was kicked out by drobo.
I replaced the drive, and all is green.

I wanted to know why the drive failed, so I did “get diagnostics information”.
The export took a few minutes, then I got an error unable to create diagnostic information, or something like that, and Windows reported that DDService.exe crashed.

My OS is Vista Ultimate x64 SP2.

After this I had to reboot my PC and the drobo before it would communicate again.

Anybody else seen this?

Here is the dump analysis, I have the dump if any devs want it:

What version of dashboard are you running?

What is the firmware on your drobopro?

Hi Jennifer.

Dashboard 1.6.6
Firmware 1.1.3

P.

Since you made another post asking about decrypting the diag file, can assume it saved successfully?

I also have never seen a crash like you described.

Hi Jennifer

Yes, after the restart I could save the file.

I still have the dump if your developers are interested.

P.

Maybe if it happens again, open a support case.
