Sequence missing values

We're using a single sequence within a schema that is called in various procedures that are run to set up a database. THe sequence is owned by the schema and only one session is running on this schema. After the procedures have been run it appears that the sequence has been missing certain values. e.g a value that we had expected to be 1001 is actually 1009. The jump seems to be random. Does anyone have *any* idea what could be causing this. Apart from the obvious ones like somebody else getting the nextval, which is not happening.

thanks
