Default maximum number of retries when binding to a port before giving up.
Maximum number of retries when binding to a port before giving up.
When a port is given a specific value (non 0), each subsequent retry will
increment the port used in the previous attempt by 1 before retrying. This
essentially allows it to try a range of ports from the start port specified
to port + maxRetries.
