Have some issues with SME backing up Exchange and it throwing “Asynchronous call DoSnapshotSet timed out!” all over the backup log.
Well it appears that having free_space_realloc=on set on the Aggregates caused this. As soon as it was set to off, this issue went away.
That just leaves this error to be fixed
