Quoting code from anything other than the current release is pointless. 
There were connection manager fixes in 2.3.18 specifically. Upgrade to 
2.3.20 and see how it behaves. Also, something to keep in mind, the 
piece of code that exposes the problem isn't always the piece of code 
responsible for the problem, and you'll miss the actual fix if you only 
focus on the symptoms.
