uWSGI listen queue of socket full

Jonathan

I'm having an issue with my Flask app where periodically the log starts repeating

*** uWSGI listen queue of socket "127.0.0.1:xxxxx" (fd: 3) full !!! (101/100) ***

until I manually restart the process. I haven't been able to track down what causes it, and my Google searches for the error have been thin on solutions. I'm not even really sure how to begin debugging it.

Any suggestions? If it's simply a matter of getting a bigger stack and throwing more workers at it, I'm OK with that, but I don't want to spend extra if there's a better solution.

Thanks!

Jonathan Check your app log in ~/logs/app/appname to determine exactly when the problem started, then check your site access log in ~/logs/sites/sitename for that time to see what sort of traffic you were receiving when the problem started.

If you see anything that looks like abusive/malicious traffic then please pass that along via email to Opalstack support and we'll look into blocking that IP.
