I am having an issue with routers running software release 6.40.8 (bugfix).

1. Cannot create support file. It gets 60 to 80% complete then stops, never writing to the file system.
2. With SAF WS licensed radios, I am getting fcs errors every 30 seconds on ports connected to those radios. I have not seen these errors on previous software releases and have tried enabling flow control with no luck. This is very similar to the errors I have seen reference with certain UBNT radios. I have other radios from other manufactures with no errors and I have changed out all cables, certifying them with my tester.

Very frustrating.

Router: CCR1009-7G-1C-1S+
Software: 6.40.8
Firmware: 3.41

Are both ends of the link set to autonegotiate? Have they both agreed on 100-full or 1000-full? Or did was one end set to 100-full and the other has "negotiated" 100-half?
