My server gets kernel panic every 7th day

[Daniel Johansson]

Hi, i've had my server up for over a year now and it's been rock solid
but for the latest weeks the server has rebooted evert Saturday at
exact 04:19:57 because of a find command. I have no idea why and I've
checked the cron log and I don't think any crontab is runned at that
time. Not as far as I can see from the cron log. Anyway find makes the
server get a kernel panic and it reboots. This is the fourth week in a
row it happens and I've checked the hardware, no problems at all.

I'm running 4.10-RELEASE-p5 so there is nothing newer to update to.

Output from the message log:

Any idea how to find out what causes this and how to find out what is
running perl or how to fix it?
