    Description

      ZOOKEEPER-1702 tracks a client connection management bug. The bug can cause an unexpected TCP RST that ultimately prevents delivery of a session expiration event. The symptoms of the bug seem to show up more frequently on Windows than on other platforms (though it's not really a Windows-specific bug).
