Behaviour of processpool #237

Open

Hi I'm developing a web app with

Flask + Flask_APScheduler + Flask_SocketIO on the server side
VueJS on the front side.

I encounter several issue on the server side when using a process pool instead of a thread pool to run my background tasks (heavy):

The socketIO.emit calls from my jobs are not always sent to my client. Sometimes yes, others no. Not sure why.
The auto reload feature of Flask seems broken. It is stuck because of the background process not properly killed I suppose. But I know that it ended normally.

None of this behaviors happen with a thread pool.

Could any of you help me on that ?

Thanks

Owner

Hi,

I can try to investigate this further if you can provide a repository that reproduces the issue
