We had a problem where, when a member of staff tried to go to the workshop allocation page, they got a page-full of errors. (In one case enough HTML to crash their web browser!)
So, to try to get the workshop out of that state, they switched it to Scheduled allocation. That caused cron to crash. The cron output stopped here:
Processing module function workshop_cron ...... started 23:38:19 : 112.6MB
|

Starting workshop allocation methods
|
Processing cron function for workshopallocation_scheduled...
|
started 23:38:19 : 113.6MB
|
... executing scheduled allocation in 1 workshop(s) ...
|
Looking in the PHP logs, we have this error:
