no that is a redhering. In earlier cyrus versions there was only one=20=20
rolling logfile
and no channel name was needed, now you can also use rolling logs=20=20
search index and
backups. To keep old configs compatible there is the "no channel" channel

The IOERROR and the "bailing out" is the part where the real problem is.
If i remember correctly i did use strace and gdb to find the real problem

What do you mean with "fixing that sinle file"? If i remember=20=20
correctly fixing needed mulitple steps.
1. Remove the annotation from the mailbox.
2. Reset the replication for the user/remove the mailbox of user form=20=20
the destination
3. use sync_client whith "-u <userid>" to sync the user again
