ext4dev oddity

I am having some pretty good success on some different machines with ext4. However, I am getting this message: EXT4-fs error (device dm-0): ext4_mb_generate_buddy: EXT4-fs: group 717: 23410 blocks in bitmap, 23411 in gd EXT4-fs error (device dm-0): ext4_mb_generate_buddy: EXT4-fs: group 721: 19309 blocks in bitmap, 19333 in gd What do I need to do to help debug this, if anything, and how do I find out which files or directories are affected?
