Unfortunately, there’s no “getting around” this issue. Your database appears to have a 1 GB limit on it and you have hit it. It may have been created in an early ODS (ODS 20 had a 1 GB default limit, although you could choose to go as high a 4 GB), or deliberately created with a size limit. Whatever the reason, it has a 1 GB limit and you MUST make a new copy with a larger limit or you’re going to keep getting those messages. In addition, the database could become corrupted and completely unsalvageable if the B-Tree or on-disk structure corrupts, which often happens in these cases. Save yourself a lot of grief and just go ahead and fix it now. It doesn’t matter what you think it SHOULD be — you have to work with what IS.
