Hi everyone,

I'm attempting to "mysqldump" a database on a box that is hovering near
max CPU and mem usage.

When I run the command, other critical programs fail to respond causing
an 'outage-like' situation.

Normally, this is a time-of-day task and will run happily later into the
night, but I want to run it now.

What is the best way to set priority on my task in order to ensure it
completes as quickly as possible, but does not cause a situation where
other programs and their children can't respond?

Steve
