创建多个httpd服务器时，只能访问其中一个，第二个无法访问

[DJZ1992]

创建了多个httpd服务器。80、81和89三个端口

I (5207) app_httpd: Starting stream server on port: '81'
D (5217) httpd: httpd_thread: web server started
D (5217) httpd_uri: httpd_register_uri_handler: [0] installed /stream
D (5217) httpd: httpd_server: doing select maxfd+1 = 59

I (5227) app_httpd: [1605]:Starting OTA server on port: '89'
D (5237) httpd: httpd_thread: web server started
D (5237) httpd_uri: httpd_register_uri_handler: [0] installed /ota
D (5237) httpd: httpd_server: doing select maxfd+1 = 62
D (5257) httpd_uri: httpd_find_uri_handler: [0] = /ota

访问80，可以打开web，访问81也可以。
但是访问89打不开,为什么呢？

你试试把 CONFIG_LWIP_MAX_SOCKETS 调大一点。

你试试把 CONFIG_LWIP_MAX_SOCKETS 调大一点。

默认是10，这个10跟多个httpd服务器之间的关系有什么说法？

[ESP_YJM]

每个 httpd 服务器会占用起码 3 个左右的套接字，如果再有客户端连接，每个客户端就会占用一个，套接字总数就是由 CONFIG_LWIP_MAX_SOCKETS 决定的，数量不够了就无法访问了。

好的，谢谢
