For 1 in about 500 of our users, we have a found a problem with mix format INBOXes. (The problem isn't restricted to INBOXes.) I'm scanning the mix architecture for anomalies after a crash (which, among other problems, dumps blocks of NULs in several files). We expected to find only folders corrupted by the crash. But we've moved the INBOXes aside or restored from backups. And even the fresh INBOXes are found in followup scans. And this mix DATA-NOT-REFFED problem appears on other servers. Note: $home is a generic placeholder for the output. The inboxes are, of course, in various users' home directories. I look to ensure the each .mixDATA file is referenced in the .mixindex. The messages are not accessible to the user until we run mixrbld to create a new mixindex file. It seems common that only one message is in the mixDATA file (and it's frequently large), but many unreferenced mixDATA files have several messages in them, so the architecture files ought have had referenced the file for some time. Either .mixindex has lost data or updates are have failed to add any reference. After mixrbld, a followup scan will go further checking each mixindex line, seeking into the mixDATA file and ensure the format of the mixDATA header is value and the UID and date match. So the mixDATA file is--to all appearances--clean, but the file is not reffed in the .mixindex (until the mixrbld). Do you have any thoughts/advice to offer?
