This may be computer related.

Buffer overruns - I set the DAQ buffer size to 10X what it nominally is at 
25KHz. If your computer cant rip data fast enough for this huge buffer, 
something is wrong. Check CPU cycle time, close other applications.

Out of memory - Reduce the length of your persistent, on-board data buffer.

I'm going to mark this as resolved because 

1. It is related to the users computer, which we cannot control
2. We added hardware options to control the ADC and DAC polling speeds. Having 
more frequent reads will likely help because the callbacks that pile up when 
the computer is temporarily taxed will not be required to handle MBs worth of 
data.
