Description

When outgoing messages are queued, OutboundTcpConnection checks the size of backlog, and if it gets more than 1024, it drops expired messages silently from the backlog.

expireMessages() just checks message's timeout, which can be request_timeout_in_ms (10 sec default) for non- read/write message, and does not check if its droppable.
