Dear experts, I've a strange behaviour with uWSGI and supervisor.
This is my settings in galaxy.ini file: [uwsgi] processes = 3 socket = 127.0.0.1:4001 stats = 127.0.0.1:9191 #socket = /var/log/galaxy/uwgi.sock pythonpath = /home/galaxy/galaxy/lib pythonhome = /home/galaxy/galaxy/.venv threads = 4 logto = /var/log/galaxy/uwsgi.log
And this is my supervisord settings: [program:galaxy_web] command = /home/galaxy/galaxy/.venv/bin/uwsgi --ini-paste /home/galaxy/galaxy/config/galaxy.ini directory = /home/galaxy/galaxy umask = 022 autostart = true autorestart = true startsecs = 20 user = galaxy environment = VIRTUAL_ENV="/home/galaxy/galaxy/.venv",PATH="/home/galaxy/galaxy/.venv/bin:%(ENV_PATH)s",PYTHONHOME="/home/galaxy/galaxy/.venv" numprocs = 1 stopsignal = INT startretries = 15
The problem is that when I run galaxy with "supervisorctl start galaxy:" I've 4 galaxy process (ps -aux | grep uwsgi): galaxy 28795 13.0 1.0 1465320 177332 ? Sl 16:42 0:12 /home/galaxy/galaxy/.venv/bin/uwsgi --ini-paste /home/galaxy/galaxy/config/galaxy.ini galaxy 28950 1.2 1.0 1465320 170108 ? Sl 16:42 0:01 /home/galaxy/galaxy/.venv/bin/uwsgi --ini-paste /home/galaxy/galaxy/config/galaxy.ini galaxy 28951 1.1 1.0 1465320 170108 ? Sl 16:42 0:01 /home/galaxy/galaxy/.venv/bin/uwsgi --ini-paste /home/galaxy/galaxy/config/galaxy.ini galaxy 28953 0.0 1.0 1465320 166060 ? S 16:42 0:00 /home/galaxy/galaxy/.venv/bin/uwsgi --ini-paste /home/galaxy/galaxy/config/galaxy.ini
Once I did "supervisorctl stop galaxy:" I've: galaxy 28953 0.0 1.0 1465320 166060 ? S 16:42 0:00 /home/galaxy/galaxy/.venv/bin/uwsgi --ini-paste /home/galaxy/galaxy/config/galaxy.ini
there is still a uwsgi process (sometimes more, it depends on the uwsgi process number). I'm able to stop only those processes which have a "Sl" in the STAT column of "ps -aux | grep uwsgi": S Interruptible sleep (waiting for an event to complete) l is multi-threaded (using CLONE_THREAD, like NPTL pthreads do) (ps wiki)
The problem is that I can't stop all the uwsgi processes, therefore I'm unable to restart galaxy, without killing all uwsgi processes.
Thanks a lot, Marco.
