Hi all. I have a question about cron jobs that seem to be running to
long or with multiple copies of itself. For example, I have a backup
script that I run that seems to make multiple copies of itself. If I
view the running processes I see numerous instances of the same cron
job. Is there something I can do to limit this from happening? When it
does, it drains my CPU and some of my other processes are non
responsive. Any help would be appreciated. Thank you.
That's not the to cron to do that.
Actually, it could be. If the script is started by cron and is still
running when the next job is scheduled, cron will start another process.
If they're both still running when the next job is scheduled, you'll have
three processes running, etc., etc.
The first thing I would do is run the script manually and see how long it
takes to complete. Then set your cron jobs up to run with enough time
between them for the script to complete and exit before the next job
starts.
