Cron that needs more time than he's allowed to

Question

My crontab runs a cron every 5 minutes... If the cron needs more than 5 minutes to run, can this be a problem?? Can the problem be with the commands the cron runs?

Thanks for your answer ;-)

Answer 1

cron should have no problem running your task again even though the first one isn't finished.

Although, a problem could arise depending on the commands you are running (i.e. if they both write to the same file)
