Hi Bill,
You should regard the debounce as a 'sticky plaster' rather than a cure. The fact that increasing it to 500 created improvement I think confirms that you have a problem with electrical noise which should now be tackled.
Ideally, you should be able to run your system with debounce set to zero but the 500 figure that I suggested generally protects against the odd EStop caused by mains borne spikes etc.
Check that your shielding and earthing are all good.
