What was the previous version you were running? 2.3.20? I don't think there are really much of any changes related to dbox or index file handling. We did do pretty large fixes to mdbox corruption handling, but looks like they're still waiting for v2.3.22 release. Maybe those would help with these inconsistency issues also, or at least fixing them.
