Open Stack

In my case, the base OS is 12.04 Precise.

The problem is intermittent in that it takes maybe 15 to 20 cycles of unstack/stack to get it into the failure mode, but once in the failure mode, it appears that tgt daemon is 100% dead-in-the-water.

What base OS? A change was made there recently to better handle debian because we believed (possibly incorrectly) that precise actually had working init scripts.

It would be interesting to understand if this was a 100% failure, or only intermittent, and what base OS it was on.
