Sounds like you are doing too much in a loop.  You must fetch samples fast enough to avoid buffer overruns.  If you save data in the sam loop as the fetch this becomes a distinct possibility, especially with more channels high acq rates.  Your fetches become large so writing to file can be slow causing your next fetch to not be in time.  Post your code or take the save out of the fetch loop and see if the error goes away.  if so, there are multithreaded workarounds.

Thanks for your suggestion, I take out the save and run the multi fetch, the problem is still there, Appreciate your help.
