Before Creating the Bug Report

• I found a bug, not just asking a question, which should be created in GitHub Discussions.

• I have searched the GitHub Issues and GitHub Discussions of this repository and believe that this is not a duplicate.

• I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ.

Runtime platform environment

CentOS Linux 7 (Core)

RocketMQ version

rocketmq-all-5.1.4

JDK Version

java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)

Describe the Bug

在生产场景中，发现了堆内存溢出，业务量并不大。

内存堆栈

Steps to Reproduce

针对ha端口10912进行高频探活，压测时间一长即可出现。

-- coding:UTF-8 --

import sys
import socket
import time
sys.path.append(".")
def tcp_health_check(host, port):
now = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
try:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(1)
sock.connect((host, port))
sock.sendall(now.encode())
print("{}TCP连接成功:{}:{}".format(now,host,port))
sock.close()
return True
except socket.error as e:
print("TCP连接失败: {}".format(e))
if sock:
sock.close()
return False

def main():
host = '127.0.0.1'
port = 8081

while True:
    result = tcp_health_check('127.0.0.1' , 10912)
    time.sleep(0.5)

if name == "main":
main()

What Did You Expect to See?

探活不应该造成broker内存溢出

What Did You See Instead?

应该针对这种异常场景进行风险规避，通过堆栈和ha逻辑确认，在haconnection建立，进行Read/WriteSocketService线程的启动，和追加connection到列表的顺序里面，存在先删（Read/WriteSocketService run方法执行），后追加的风险。
