mcdullbloom opened a new issue, #6799: URL: https://github.com/apache/apisix/issues/6799
### Description I also got the warning "upstream node has been specified, cannot be set repeatedly" and several 404 response as well(the qps is about 800) . I added some logs in set_by_route and udp-logger and found that apisix forward the request to wrong backend upstream node. I susspect that the api_ctx is polluted but I have no idea why this happen. PS：we do not use the plugin "traffic-split" ### Environment apisix version (cmd: apisix version): 2.4 OS: (cmd: uname -a) linux 3.10.0-693.el7.x86_64 CentOS Linux release 7.4.1708 (Core) OpenResty / Nginx version: (cmd: nginx -V or openresty -V) nginx version: openresty/1.19.3.1 -- This is an automated message from the Apache Git Service.
