I doubt there is anything wrong with the sequence. Do the records you
are importing already have an which could be coming from somewhere
other than the sequence you mentioned? If the imported records have a
value for this column, the sequence will not be advanced. Are you
doing inserts anywhere where the ID value is provided rather than
using the sequence value?
