> Under heavy load and many threads (>30) the C++ Native client tends to open a lot of connections which, if the idleTimeout is not relatively small, could provoke client port exhaustion.
> The reason for this uncontrolled creation of connections is the implementation of the thread managing connections (ThinClientPoolDM::cleanStaleConnections()) that, in order to determine which connections to close due to timeout or load conditioning, gets all the connections from the pool for some time. Threads requiring a connection when this operation is fired, will create new connections while the maximum is not reached.
> The proposed solution consists of changing the implementation of the cleanStaleConnections so that it does not get all the connections at some point but instead, takes one at a time in order to determine if it should close it.
