[MapProxy] Max file size for mapproxy.yaml

[Pratt, Jerald R (IS)]

Is there a max file size for mapproxy.yaml?  Is there a way to test/check to see if the file size is causing mapproxy to crash?

I have scripts that creates entries in my mapproxy.yaml file.  All works well but at some point as the file size grows I start to get errors when the file is being read.  I have been using the demo page to verify that my map layers are working.  When things go bad, I get a 500 error in my browser.  Looking in the my httpd ssl_error_log file, I see the follow error messages:
