Howdy Guys,
I have a PHP backup script running as a cronjob that has an exec(mysqldump)
line followed a bit later by an exec(tar -cjf) line. The backup script runs
against a slave db in the wee hours, and the master gets a continuous stream
of inputs at the rate of about 18,720 per day.

exec() runs its own little mini-not-quite-shell, so as soon as it
ends, the
Thank you Jon, Joe, and Richard.
I guess I'll leave things as they are and continue to monitor daily.
Fortunately, only up to 3 years worth of data needs to be kept live in the
master-slave db's, so there is a limit to how much data I will have to cope
with.
