Cron the Eater of (CPU) Time

Note: This behaviour was observed on a Pi B+; it was not observed on a Pi 2.

I happened to have top up while doing the bonded Nic test and noticed that the load was awfully high. Then the following popped up:

cron1

Cron pretty much has the CPU pegged.

Once I saw this, I wondered what on Earth cron could be doing that was so intensive. So I looked in /var/spool/cron/crontab and it was empty.

A few minutes later this followed:

cron2

It was still roughly eating 1/2 the CPU time.

So I rebooted and observed the same behaviour.

I then did a sudo service cron stop and started my tests from scratch…..
