Hi,
This type of problem is reported quite regularly - It is because the volume
field is defined as type int and will overflow if the volume gets too large,
resulting in strange numbers. The usual fix is to divide by 1,000 when
working with very large volumes. Tomasz has said it will be changed in a
future version to hold larger numbers.
