Zero8 + Traktor Pro Problem

[llavoe]

I use my Zero8 with Traktor Pro. I record my mixes using 5L + 5R on my mixer into Channel A on Traktor. After 70 minutes or so, the mixer freezes up into a screeching sound on whatever Decks are playing in Traktor. The program is not freezing, it is definitely coming from the mixer. I have not had it freeze when not recording. It has happened to me about a half dozen times this past weekend. The only way to stop the sound is to reboot the mixer.

Is anyone else having this happen to them? If so, is there a fix?

I use version 1.6 on the firmware and traktor is up to date.
