It turns out the issue isn't only the "rm -rf", so I've eliminated
that. The process is creating many subdirectories and files.
Here's the output that you requested. I've generated the output
at a "baseline", 1 minute into the process, and then every 4 hours.
Sorry for the flood of information but I figure "more is better".
You can look at the first and last items if you prefer.
I really appreciate the help!
