I've been moving users from one system to another by doing a dsync mirror operation. The first dsync mirror takes some time, because of the number of users involved, so I am doing an initial sync, and then I direct the users to the new location and do a final 'freshening' sync to get any changes that happened during the longer sync.
The problem seems to be with this freshening sync, it seems quite fragile breaking with things like: dsync-local(u...@example.com): Error: msg-get failed: box=Spam uid=3034

You may want to run dsync again. those final "Unexpected finish reply" and "Unexpected reply from server" are a bit surprising results. Running dsync again seems to resolve things, but there seems to be a bug here that is causing unexpected results to leak through to the dsync process? thanks, micah
