kuberxy opened a new issue #4403: URL: https://github.com/apache/apisix/issues/4403
### Issue description 我们的系统出现了“消息发送多次”的问题。请问apisix是否会在一些情况下向后端节点发送多次请求？又或者我能否通过一些方法排除是apisix的问题 ### Environment Request help without environment information will be ignored or closed. * apisix version (cmd: `apisix version`): $ apisix version 2.2 * OS (cmd: `uname -a`): $ uname -a Linux hz-i-node2 4.15.0-135-generic #139-Ubuntu SMP Mon Jan 18 17:38:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux * OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`): $ openresty -V nginx version: openresty/1.15.8.3 built by gcc 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04) built with OpenSSL 1.1.0l 10 Sep 2019 TLS SNI support enabled configure arguments: --prefix=/usr/local/openresty/nginx --with-cc-opt='-O2 -O2 -DNGX_LUA_ABORT_AT_PANIC -I/usr/local/openresty/zlib/include -I/usr/local/openresty/pcre/include -I/usr/local/openresty/openssl/include' --add-module=../ngx_devel_kit-0.3.1rc1 --add-module=../echo-nginx-module-0.61 --add-module=../xss-nginx-module-0.06 --add-module=../ngx_coolkit-0.2 --add-module=../set-misc-nginx-module-0.32 --add-module=../form-input-nginx-module-0.12 --add-module=../encrypted-session-nginx-module-0.08 --add-module=../srcache-nginx-module-0.31 --add-module=../ngx_lua-0.10.15 --add-module=../ngx_lua_upstream-0.07 --add-module=../headers-more-nginx-module-0.33 --add-module=../array-var-nginx-module-0.05 --add-module=../memc-nginx-module-0.19 --add-module=../redis2-nginx-module-0.15 --add-module=../redis-nginx-module-0.3.7 --add-module=../rds-json-nginx-module-0.15 --add-module=../rds-csv-nginx-module-0.09 --add-module=../ngx_stream_lua-0.0.7 --with-ld-opt='-Wl,-rpath,/usr/local/openres ty/luajit/lib -Wl,-rpath,/usr/local/openresty/luajit/lib -L/usr/local/openresty/zlib/lib -L/usr/local/openresty/pcre/lib -L/usr/local/openresty/openssl/lib -Wl,-rpath,/usr/local/openresty/zlib/lib:/usr/local/openresty/pcre/lib:/usr/local/openresty/openssl/lib' --with-threads --with-dtrace-probes --with-pcre-jit --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_v2_module --with-http_stub_status_module --with-http_realip_module --with-http_addition_module --with-http_auth_request_module --with-http_secure_link_module --with-http_random_index_module --with-http_gzip_static_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_ssl_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module --add-module=/home/cyadmin/downloads/openresty-1.15.8.3/bundle/ip2location-nginx --add-module=/home/cyadmin/downloads/openresty-1.15.8.3/bundle/nginx-sticky- module --with-stream --with-stream_ssl_preread_module * etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API): Stand-Alone. not use etcd * apisix-dashboard version, if have: * luarocks version, if the issue is about installation (cmd: `luarocks --version`): $ luarocks --version /usr/bin/luarocks 2.4.2 LuaRocks main command-line interface -- This is an automated message from the Apache Git Service.
