Dare i ask if your flapping behavior happens autonegotiate synch wise something happening at the net level / forced link speed.
Some sort of interference based flapping.

Hi All,
I have a site with this projector, controlled via RS-232 thru a DM-RMC-4KZ-100-C room box (50' from the rack). It's been installed for about a couple years...
Though I do not remember having this issue initially, for the last year, we have had a condition where after ~1-3 weeks, it will stop responding to commands and also the RX/feedback stops.
Sony support says that this is common when you have both RS-232 and IP connections simultaneously, which we did, though the IP connection was only for management and Domotz pinging...We noticed that Domotz would see a tremendous amount of network Up/Down states, and then often it would just go down and stay down...
Though I think the issue with having IP and Serial connections being a problem is bogus for a professional product, we have disconnected the IP connection.
Still we've seen the issue, and it requires a hard-boot to restore the serial communications...
Anyone else see this kind of behavior??? I have another site with a 715 that we have not seen this issue with....
TIA!
