python process consumes 100% cpu

[St. Pirsch]

Hi all,

running web2py.py 2.14.6 on a mac 10.11.6 gets me constantly a 100% cpu usage on python. Is this a known issue & is there a solution?

Thanks - Stephan

Not a known issue. Do you have the same problem if you run from source?

[St. Pirsch]

Yes, I'm running from source stp$ python2.7 /Users/stp/Sites/web2py/web2py.py

After starting the server, the python process climbs to 100% cpu within a minute or so and stays there, even though the server is idle.

The Task stats look like this:

Can you try running web2py without the GUI option `--nogui`
python web2py.py --nogui --port= 8080 --ip=127.0.0.1 --password='<ask>'
Command line options, in case you want to refer to them: http://www.web2py.com/books/default/chapter/29/04/the-core#Command-line-options

Do you see the CPU issue with this?

Hey Kiran,

you are right, without the GUI there's virtually no CPU load. I suppose it's a general issue on mac.
Thank You !

[Kiran Subbaraman]

That's good to know. You could take a look at this page: https://www.python.org/download/mac/tcltk/ to understand if there are Tcl/Tk issues related to your environment. This may solve the CPU issue ... am not sure.

[St. Pirsch]

Thanks!. I tested the web2py gui on a different mac machine with 10.11.5 & it's running hot as well. I'am going to try it with the Tcl/Tk versions recommended in your link instead of the ones provided by the OS.
