Critical Description
We are using lustre 2.4.0-19chaos on our servers running with the ZFS OSD. On some of the OSS nodes we are seeing messages like this:

First of all, these messages are terrible. If you look at osd_attr_set() there are four exactly identical messages that are printed. Ok, granted, we can look them up by line number. But even better would be to make them unique.
So looking them up by line numbers 967 and 973, it would appear that we have hit at least the first two of the "filed to update accounting ZAP for user" messages.
Note that the UID numbers do not look correct to me. Many of them are clearly not in the valid UID range. But then I don't completely understand what is going on here yet.
