I'm trying to free up space in some parent databases that have no objects. In some cases, a small amount of space is left behind (e.g. 136 bytes, other DBs leave behind less than 100 bytes), and I'm unable to remove this space. This occurs on a few databases only, not all of them. I have even tried adding more space, say 1 GB, and then try and free up the whole amount, but the same small amount is left behind. I have also run the updatespace utility, but still reports this small amount of space. These database may have existed when we were on TD 14.00 and migrated to 15.00.
