Consul kv get - Connection reset by peer

现象

获取 consul kv 时抛出异常：connection reset by peer

排查

• 观察 8500 端口 ESTABLISHED 数量，达到 201
• 查询 consul 官网配置，GitHub issues，发现 http_max_conns_per_client 默认值是 200
  • http_max_conns_per_client - Configures a limit of how many concurrent TCP connections a single client IP address is allowed to open to the agent’s HTTP(S) server. This affects the HTTP(S) servers in both client and server agents. Default value is 200.
