Yeah, I saw that too. I do know the mechanism that is happening. I
just can't figure out where the problem is without inserting print
statements.

Yes, that is correct. Using curl to launch the script via the web server.

When the script starts, it prints a banner with the script name and
date/time stamp. When it completes, it is supposed to print aggregate
results, time spent. I know it's encountering this problem before it
reaches the end as not all the data gets processed. I can't tell where
it is stopping though. If I put it in debug mode, it prints out a lot
of data from the beginning of the script, and never encounters this
problem.

The way the script is designed, it depends on some $_SERVER values,
which wouldn't be set if running directly from the shell.
