[I] 疑似sharding链接泄漏 [shardingsphere]
YouSec995 opened a new issue, #33713:
URL: https://github.com/apache/shardingsphere/issues/33713
sharding版本：5.1.1
这边发现了要一些问题 我们使用gorm链接sharding，sharding来访问mysql，目前发现sharding一直在增长CLOSE_WAIT链接，同时ss -s发现tcp存在大量的closed状态的文件句柄（也是一直在增长，疑似泄漏）。
closed多的时候有好几万的，以下是我们重启sharding之后，慢慢增长的结果
23307是sharding启动的端口

You can use tcpdump to capture some tcp chains to determine which side interrupting the link.
