We are hosting a web application with configuration as below:
Application: Apache 2.4 / Python 3.4 / Django 2.0 Database servers x 6 : 32 GB / 8 cores behind load balancer Web servers x 6 : 4 GB / 2 cores behind load balancer Setup is in AWS so we are using AWS-Elastic load balancer. The application supports 2000 concurrent connections but failing for 2500 and beyond. In load testing around 1800 requests are failing out of 3.5 lakh total requests. In the apache error log we are seeing the error message as below ? [Wed Jan 02 14:05:53.349209 2019] [wsgi:error] [pid 21559:tid 139722408036096] (11)Resource temporarily unavailable: [client 172.31.12.61:51748] mod_wsgi (pid=21559): Unable to connect to WSGI daemon process 'pe-ta-dev.knowdl.com' on '/run/httpd/wsgi.21472.0.1.sock' after multiple attempts as listener backlog limit was exceeded or the socket does not exist. Any idea how we can resolve the issue ? Regards Mahesh -- You received this message because you are subscribed to the Google Groups "modwsgi" group.
