Default PT 12.4 HD and MboxPro 3 an the VideoEngine?


I´m running PT 12.4 HD with a MboxPro 3 Yosemite 10.10.5 and try to pre-mix (5.1) an 8 min short.
It´s a small session ProRes proxy nothing heavy.
The system randomly gives me the following errors.

"(AAE -6085) The audio device buffer underflowed, try decreasing the H/W Buffer Size or remove the audio firewire bus"


"The Video Engine reported an error. More information is in the Video Engine log file"

I have a look into the log file, and it says:

"Message: Cannot start playback. The network clock is not locked. Please try again"

And this I already know since the session will not play anymore and I have to either restart the session or reboot.

I can´t force it happen. So I have no clue. Anyone been having similar experience?
