State information for deterministic NAT may include source-prefix for Virtual Server that's not attached to the LSN pool.
Source prefixes from unattached VS still count against translation end-points, but would never get use since there's no listener. Therefore, under utilizing the translation space.
Deterministic NAT LSN pool previously attached to an active Virtual Server where translation occurred at least once. Disable Virtual Server or remove LSN pool from Virtual Server, state information including the virtual-server's source-prefix could continue to be logged, during translation or periodically.
Delete unattached LSN pool, or restart tmm.
Unattached and disabled VS correctly removed from LSN pool.
