Hi, Thanks for reporting. Please make sure you use the server_traffic_status_zone directive. The directive server_traffic_status_zone in stream block is essential because the shared memory zone using in nginx-module-sts, nginx-module-stream-sts is allocated by that directive. The process finding shared memory zone is as follows:

  1. nginx-module-stream-sts -> server_traffic_status_zone -> Allocate shared memory zone
  2. nginx-module-sts -> stream_server_traffic_status_display -> Find shared memory zone
