Our /var/log/messages is flooded with these records:

Try to disable all of your custom cron jobs, then enable it one by one and see which one is guilty - then inspect it's code.



Funny thing that CLI script causes huge web server load.
Does any of your cron jobs is making connection with any website on the same server? E.g. using curl, webapi?
