Hmmm... There is a conceptual issue. Connection pool tells you that it could
not obtain connection during blocking timeout you have specified. This is
consequence of the "reconnect" feature of the pool - if server for example
is out, pool will try during blocking timeout few times, in hope that server
comes back. The actual error that happens during obtaining the connection is
written in the log.

I will check how hard it is to provide a better error handling.
