Re-indexing causes "maximum open cursors exceeded"

We have a few issues with this re-indexing ...
CONF-3977 (http://support.atlassian.com/browse/CSP-1450)
and now this.

Basically, when we re-index, we end up running out of cursors - get loads of the errors below:

We had to set the number of open cursors limit (limit per connection) to the rather ridiculous value of 2000 before we could get a successful re-index completion.

And when the re-index was completed, we had 5518 open cursors remaining... which kinda suggests some kind of leakage...

So, I am not sure if the two are related... but I get the feeling they are...
