Do not enable `SO_REUSEADDR` when binding a socket to an ephemeral port. On some operating systems, enabling `SO_REUSEADDR` when binding to an ephemeral port allows the system to chose a port in `TIME_WAIT` state. The version of Linux used in our CI is one such operating system. This causes two problems: 1. The system can bind to a port that is still waiting for data from a previous connection, including connections that have nothing to do with Geode. 2. Much of our test code, and some of our production code, deliberately puts ports into `TIME_WAIT` state in order to "reserve" them for later use. If `SO_REUSEADDR` is set when binding a socket to an ephemeral port, the system may bind to a port that other code has reserved for some other purpose. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
