Bug Report

Reids uses the domain name, and lettuce uses the UDP protocol to occupy two random ports.

Current Behavior

netstat -tunlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 182.10.21.136:8088 0.0.0.0:* LISTEN 519/java udp 0 0 0.0.0.0:53578 0.0.0.0:* 519/java udp 0 0 0.0.0.0:59364 0.0.0.0:* 519/java

The UDP port is not released. After the restart, the port changes.

[qqhai007]

The underlying DNS protocol uses UDP, why the port is not released.
