> Hello all,
>
> When I use redis with gevent and uwsgi, some of my processes seem to hang.
> I’ve isolated the error I’m getting in the code snippet below.
>
> When I use the following command ( uwsgi --gevent 100 --socket
> 0.0.0.0:8000
> --protocol=http -w testapp -p 4 ) to have uwsgi run 4 workers I expected
> 'done' to be print 4 time to standard output, but it doesn't. If I remove
> the monkey patching, things works fine and I get the 'done' to print 4
> times. When I use one process, everything works find, but anymore then
> that
> and I would get the hanging problem.

> Any help would be appreciated.

you cannot share the redis socket between processes, you need to make a
new connection for each worker. You can use @postfork decorator or just
add --lazy-apps to initialize your code for every worker
