I switched back to TCP sockets and get this in uwsgi output in production: Mon Feb 14 15:18:27 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:28 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:29 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:30 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:31 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:32 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:33 2011 - *** uWSGI listen queue of socket 4 full !!! (129/128) *** Mon Feb 14 15:18:34 2011 - *** uWSGI listen queue of socket 4 full !!! (128/128) *** SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request /status !!! write(): Broken pipe [plugins/python/wsgi_subhandler.c line 186] I'd like to monitor the listen queue, in order to diagnose if we are constantly "near the limit", or if it is an "accident". Can you export the variable please? BTW what's the status of the syslog support? Can I use --log-syslog reliably, and get the above messages at warn or err level? This would be really nice!
