[web2py] Fatal Python error: Couldn't create autoTLSkey mapping

[Richard Penman]

hello,

I set up a uwsgi / nginx server using 
the setup-web2py-nginx-uwsgi-ubuntu.sh script.
However I find when the app tries to start a sub-process I get this error:

Fatal Python error: Couldn't create autoTLSkey mapping

I read around and apparently this can happen when lack of memory.

Do you see any problems with these uwsgi settings:
<uwsgi>
    <socket>/tmp/web2py.socket</socket>
    <pythonpath>/var/www/web2py/</pythonpath>
    <mount>/=wsgihandler:application</mount>
    <master/>
    <processes>4</processes>
    <harakiri>60</harakiri>
    <reload-mercy>8</reload-mercy>
    <cpu-affinity>1</cpu-affinity>
    <stats>/tmp/stats.socket</stats>
    <max-requests>2000</max-requests>
    <limit-as>512</limit-as>
    <reload-on-as>256</reload-on-as>
    <reload-on-rss>192</reload-on-rss>
    <uid>www-data</uid>
    <gid>www-data</gid>
    <cron>0 0 -1 -1 -1 python /var/www/web2py/web2py.py -Q -S welcome -M -R
