Thanks for the file. So I can reproduce the issue you're seeing around frame 400, but it's going to be really tough to debug considering it doesn't appear until hundreds of frames into a heavy sim, and it's likely dependent on a single numerical value somewhere in tyFlow's simulation pipeline going haywire. That type of issue is really, really tough to track down.
One thing I did notice is that if you disable all of the operators that are sending the particles to the Delete event, the bug doesn't seem to occur any more (at least, it didn't occur up until frame 500 - I didn't simulate further with them off)....so it might be related to the deletion of your cloth particles. Furthermore, I tried deactivating/stopping the particles before deleting them, and then I couldn't repro the bug even until frame 800....so maybe that's something to explore as a workaround (add a Particle Switch (deactivate mode) and a Stop operator to Event_006 before the Delete operator).
Just a general question about this setup: your timeline is 3100 frames long...is the machinery meant to move around in space at a given point in your full file or do anything that would prevent you from just setting this up as a loop? Seems like just making a 100-200 frame loop of the particles moving along that is repeated over time would be a better alternative than simulating 3k frames.
