I am using the new connection pooling in my module for accounting/authentication against couchbase ( https://github.com/leprechau/rlm_couchbase ).  This was working very well until I rebuilt recently (yesterday) against the latest release_branch_3.0.0 branch.  I am now seeing the below errors in the logs that cause radiusd to crash.

Wed Aug 28 15:39:30 2013 : Info: rlm_couchbase (couchbase): Closing connection (16): Too many free connections (23 > 20)

Wed Aug 28 15:39:46 2013 : Info: Bad talloc magic value - access after free 

I cannot reproduce it with -X or -xx but can see it plainly when started normally.  I also cannot seem to reproduce it if I set the pool start/min/max/spare all to 1 in my module configuration.  Has there been a change in the connection pool API that would require a change in my code using this API?
