Debugging and understanding exceptions ?

Could any one explain me the meaning of the following exception ??
time: 2013.168195 exception: Exception Caught in FixedResource::frgetvar(fsnode* flowitem, int varnum)
time: 2013.168195 exception: Exception Caught in MultiProcessor::OnTimerEvent(fsnode *involved, int code, char *datastr) object: /Bed 4
time: 2013.168195 exception: Exception Caught in ObjectFunction214__project_library_FlexsimObject_b ehaviour_eventfunctions_OnTimerEvent object: /Bed 4 class: /Bed 4

Could you post the model, or send it to support if that's not an option?

Sure.. I d email the model to the support site.. Btwn I might be able to figure it out if you could tell me how to read this error.. I mean what means what exactly.. Thnks for replying though.. appreciate it

The only thing I would guess is that the process finish event is firing for an item that had been moved or destroyed. Are you doing anything to interfere with the normal behavior of the multiprocessor called Bed 4 ?
