It's set with python-path of the deamonprocess directive.

I see, but the question is why the python-path configuration is
corrupted (one time it's empty but another time it's
\x957Q\xb7`\xb51\b\xff\xff\xff...).
Nothing was changed in the configuration, the app was restarted because
of timeout inactivity. Indeed, if i restart apache it start again
without problem.
