Thanks. I will check again for spaces. What is 'bom sequence'?

I don't know what you mean by calling it over tcp/ip. It is set up via
cPanel and runs automatically on the domain host server.

Do you mean putting the connection script directly into the cron
script rather than using an includes()?

The folder on the production server is outside of the 'public_html'
root folder so I cannot dorectly run it in my browser. I have to test
it inside another folder on my local server.

The domain host has the cron job in a folder that I can upload to. The
error_log there has the same warning message that was sent. I do not
see any syslog. I do not know what splunk is.
