Cron MiBError Error with WHMCS

Good evening, I am experiencing an error with the WHMCS Cron. When running from the terminal access command line it is failing at 3/4 Executing System Queue. I have posted the output below. If anyone has any help that would be great, WHMCS support so far have not replied since Thu.
