Usually this is because the dumping application can't provide data quickly enough. It can also be due to slow disk being used for the split buffer. As an aside, sometime in the release *after* 3.1 we're planning to remove the need for a disk buffer, since most tape drives can now give an indication that they are near the end of the tape, allowing Amanda to finish every part cleanly.
