I'm not saying that's where the error occurred, since I couldn't track
what happened. I'm just looking for places where it could have occurred.
Note that the add occurred on server 0, while the broken cookie was cooked
on server 1 when the two were playing mirrormode. So the one acting as
consumer didn't commit anything, and my guess is that for this reason it
hadn't any maxcsn available.
I note that test050 tests mirrormode in refreshOnly; is mirrormode
supposed to work in refreshAndPersist as well? The test seems to work as
expected...
