uWSGI hanging

[shitiz bansal]

Hi,

I have nginx+uwsgi+django configured on my linux servers.

Sometimes when I restart/start my servers the processes get stuck. It comes back after a few restarts.

My uwsgi log shows-

uwsgi socket 0 bound to UNIX address /tmp/uwsgi_watchman.sock fd 3

Python version: 2.7.5 (default, Mar 28 2014, 00:06:17)  [GCC 4.8.2 20131212 (Red Hat 4.8.2-7)]

Set PythonHome to /usr/lib/pyve/

added /watchman/watchman/deploy/ to pythonpath.

Connecting and reading traceback sockets gives a blank.

I am using upstart to launch uwsgi.

The init script is-

start on runlevel [2345]

stop on runlevel [!2345]

respawn

exec /usr/bin/uwsgi --touch-reload /watchman/watchman/hero --py-tracebacker /tmp/tbsocket --enable-threads --master --processes 10 --threads 15 --logto /var/log/uwsgi.log --home /watchman/watchman/ --socket /tmp/uwsgi_watchman.sock --chmod-socket --module watchman_wsgi --pythonpath /watchman/watchman/deploy -H /usr/lib/pyve/ --max-requests=500  --harakiri 300 --harakiri-verbose --reload-on-as 2048 --worker-reload-mercy 5

Please help.
