run-parts: /etc/cron.daily/vpbx_clean_old_logs exited with return code 123

Hello,

I have a new install of VitalPBX 4.5.
This morning, I got an email with the following:

Subject: Cron root@vitalpbx test -x /usr/sbin/anacron || { cd / && run-parts --report /etc/cron.daily; }

run-parts: /etc/cron.daily/vpbx_clean_old_logs exited with return code 123

Is this something to be concerned about?
How do I correct this?
