5dmk2 - capture pending

[whitesockcat]

Hello

I am shooting with a 5dmk2 (latest firmware) tethered to 6 core MacPro (OS 10.6. using Capture One v 6.2.1

Randomly, files stop transferring to computer - the pending bar, in the "camera tool" stops. For example, I can shoot about 100 frames without issue, stop shooting, shoot one frame, and it locks up. I have to pull the battery from the camera to get it to reset.

I dont know if it's the camera, capture one, or the computer

Any suggestions would be appreciated
Thanks

I'd first check the cable. I have had issues with poor cables doing remote long exposures for amateur astronomy purposes. This type of problem can have many causes, but the cable is at least easy to check.
