I have been encountering the exact same behavior, but not all the time.
My experience has also been that actual voice traffic over the repeater or to and from a connected reflector appears to work flawlessly.
One additional issue not enumerated above is that my hotspots are no longer able to link to the gateway with IcomGateway.? This worked flawlessly with QnetICOMGateway.? This is useful so that I can monitor the repeater at work or while traveling.
