Jp:
Is the sequence cached? Check out Note:62002.1 on Metalink - "Applications
which use Oracle sequences which have the CACHE option enabled  will often
'skip' values.  This article discusses the cache option, why numbers can be
lost and how to minimize this occurrance." You'll either want to pin it
using DBMS_SHARED_POOL.KEEP (depending on your version of Oracle you may
need a patch to enable pinning of sequences) or not cache it.
