jiberish output in mail from cron

[Johan Hendriks]

I am running cron jobs on multiple machines, and the output is mailed to
our support department.

But the output contains some jiberish text.

In this example is is from a cronjob that deletes some old snapshots.

Then again about 50 lines OK and then again some jiberish text and so on

the cronjob is as follows.
0       8       *       *       *      
/root/scripts/zfs-clean-snapshots.sh -d 14 -p rsnapshot-2015

I have this on multiple machines.
Is there a buffer I hit or something
