web2py single-scheduler never starts up

[juushya]

Hey Kurt,

I have checked out recent Kvasir and web2py code 3 days back. When I start web2py with -X option, it starts up fine. If I do not use it, web2py attempts to start scheduler but never gets it through.

# ./web2py.py -a test -K kvasir

starting single-scheduler for "kvasir"...

..... At this point, it just sits there and does not start up.

Thanks.

I don't see the same problem on OSX. I am seeing a problem when starting more than one scheduler (kvasir,kvasir,kvasir).

You shouldn't need to use the -a option when using -K as it's not starting a web server.

I took off -a option. It doesn't start still. This is not urgent. It still works fine with -X. So no hurry. Thanks.

I'm curious if this is a web2py issue or something that our code is causing. It's really weird how a single thread works (in my testing) but multiple do not. I'm assuming you're using Ubuntu. Can you paste your "python -v" result?

Sure :
