This is the strangest thing I've encountered yet. I thought the
original problem was the "-f" in the command, so I removed it.
Still, every couple days the command that runs the PHP script
fails to execute. Since no log is generated, I don't know what
else to do to diagnose this. If I run the script from the
terminal, it always works, creates the report and mails it. I've
even looked in syslog for when the cron job runs, and it indeed
runs to completion with no errors. Suggestions as to how to trace
this one down most welcome.
