Description

While running a single-router configuration against the wrk HTTP load generator, if the HTTP client drops the connection before the server has completed the response then the server becomes unreachable.  In other words the connection to the HTTP server becomes blocked indefinitely and requires a restart of the connection to recover.

To reproduce use the nginx/wrk 1 router configuration from:

https://github.com/kgiusti/dispatch-tester/tree/master/benchmarks/test-configurations/http1-perf

 

Run the wrk test for a short period with a large response message:

 

wrk -c 2 -t 2 -d4s http://127.0.0.1:8000/t1M.html
