Thanks Forrest, let us know what you find. I can confirm that I have done the power cycle on the Rack injectors....we have seen the same issue occur again...feels like interference.
It has been suggested by some to switch to Autosync+Freerun to avoid loss of client use...I guess it really depends on your networks reuse scheme. Internet. Phone. TV.
