FYI, in case it helps you any - I found that a "fast" restart of openfire causes this every time, but if you leave it down for a while (over 30 seconds by default I think) between 3-4, 8-9 - it is more generally able to come back online.

I thought I had opened a jira issue on this, but can't seem to find it now.
