Skipped groups in idmap2 on a cluster (with CTDB and GPFS)

Has anyone seen cases where group numbers have been skipped (ie, not allocated).

We are allocating numbers up in the range 16777216 and up.

I am investigating a problem and I find that the output from wbinfo -G
from 16777309 to 16777320 shows a gap of unallocated GIDs from
16777310 to 16777313.

However, there is a file/dir that was created via Samba that has the
GID 16777312 in its ACL.

Any suggestions on what has happened?
