In that case, I'd check your log to see what messages are getting added to syslog when it happens, and see if there's any clues there.

All it needs is for cron to run a job that does something that makes heavy use of the CPU - remember, it's not the program that starts the rogue that causes the problems, but the rogue itself, and the rogue doesn't care how it gets run.
