Hi all, I'm using nginx as a Revers proxy to a service (A). nginx receives a large number of persistent connections from a single client service(B). Service B sends a lot of requests (2K rps) over these persistent connections.
The amount of memory nginx uses seems to increase as a function of 'keepalive_requests 2147483647' . The memory used keeps raising until the machine runs out of memory (4GB, aws instance). While a smaller ''keepalive_requests 8192' doesn't create the exact problem. Some additional observations: When I reload nginx the memory usage comes down and then slowly starts building up. when I test nginx with a gatling test tool as a client, this behaviour is not observed. When I use the actual service(B), this behaviour seems to reappear. I curious to know what exactly is happening and how can I fix this issue of high memory usage ? my nginx server side configuration looks like: server { listen 443 ssl default_server; ... ... location / { # keepalive_timeout 14400s; # keepalive_requests 2147483647; ----> over 10 hrs, memory usages go to 4 GB keepalive_timeout 600s; keepalive_requests 8192; proxy_pass http://ingress; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Connection ""; } .. } Thanks for all the help, Posted at Nginx Forum: https://forum.nginx.org/read.php?2,280505,280505#msg-280505 _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
