This is a warning you usually get when you have white spaces or bom 
sequence in your files. Check all your files that are used, that they do 
not have anything before or after the PHP tages (<?php and ?>).

As you are anyway running a cron job, why do you call it over tcp/ip?

I would recommend you to rewrite the cron job to just connect to the 
database and do it's job, do have error handling in the script which 
gives you proper explanations why something goes wrong if something does 
that. A good thing is also log to syslog so you can see the job has been 
properly done and you can also forward that to splunk or similar.
