Hardware/Software Audible "Loop/Cue Freeze"

Hi Everyone,

For starters, my setup:
MBP Retina (Mid-2014), i7, 16GB RAM
2 x XDJ 1000 paired with DJM900 NXS.
RekordBox 3.2.2

I've placed the Pioneer Technical Q&A at the the foot of this post.

After about two hours of playing without issue, a track would reach the end point of the song (about 30 seconds out) and then suddenly the track would become "locked." Specifically, playing seems to become stuck in a loop that is shortened to the point where it becomes audible noise (analogous to a high-speed LFO). As you can imagine, the sound isn't pleasant. Once this occurs, I can move the platter and see a reaction with the wave form, but the playhead remains in place (as does the sound). Attempting to exit the loop yields no results. Even stranger, I can see on the wave form a "C" for the hot cue and a bright right triangle. What's strange is that I haven't set these cue point either live or pre-DJ set in RekordBox. Even more strange–this has occurred with several tracks, all of which are quite healthy (i.e. not corrupt, torrented, low kbps, etc.).

I've tried to emulate the behavior in order to replicate the problem, but unfortunately it's too unpredictable. I've narrowed it down to the fact that it occurs about 1.5 to 2 hours of consecutive playing. Furthermore, I'm not able to replicate this behavior in HID when using Traktor, so I think there's something going on with regards to the hardware/software communication between my XDJ's and Rekordbox.

Has anyone experienced something similar? Is this something that was addressed/corrected in RekordBox 4 (full disclosure, while I've been using RB4 in private, I have yet to use it in a performance setting as I typically wait a couple months before doing so, as is best-practice). Or am I just crazy? :-)

Regardless, I was able to carry-on and playoff the mishaps, though ideally I would prefer to not have to deal with them–my fear being the noise that occurs when the "freeze" happens is could potential zap my lovely audio system.

Cheers.
