Question Firing Pull Requirements when Queue is Full

I am trying to model a line where two processors pull from the same queue. The processors run on a defined time schedule and are at times both "down". When this happens the queue typically fills up and processes upstream will shut down. Once the model has reached the time to run the processor(s) again they won't pull any items. Does anyone know how to fix this. I feel like I need something in the background saying every second check the requirements again.

Default How is it setup?

Matthew,
What you are saying should be easy enough to do I'm not sure what problems you are running into really if you set up the queue and two processors and have them run off time tables and as long as those time tables have the right settings it should run the way you expect my recommendation is to post a simple file of what you're trying to do and I'd be happy to take a look at it to see if I can find anything that might be messing up the behavior.

Hello Matthew,

I have tested a similar model, but I can't detect your behaviour. I have tested MTBF/MTTR and Timetables.

Attached you find my model StartPullAgain.fsm. Perhaps you can post a similar simple model of your problem, as Ryan suggested.
