That is working as expected. When nextval() is called, a number of sequence numbers are reserved (by default one, you can set this with the CACHE clause of CREATE SEQUENCE). If the transaction is aborted, these entries won't be used. So if there were 30 inserting transactions when your server went down that got aborted, that would explain the behaviour quite nicely. This should not be a problem.
