Does anyone know if a scheduled script has a time limit or something? I have a scheduled script that does some heavy processing, and reschedules itself if it gets close to governance limits. At a certain point it just gets an 'unexpected error' when creating a case. All log statements around the case.save() indicate the data is correct, and there are no user events on the case record that show errors. Has this happened to anyone else?

We have a sked script that does some heavy lifting on Sales Orders. We have from time to time rec'd the same Unexpected Error. As far as I can tell they happen when a user is modifying a sales order that is modified as well by the saved search within the sked script.
