Here's the error. At the time there were no other snapshots in use. I do have multiple snapshots each assigned a different task should I need more than one task at the same time.

2010/01/08 16:35:50 Replication_mgr:Synchronization to 192.168.0.202 failed. Error 87 : Snapshot overflow error. Partial transfer due to error.

I watched the snapshot usage go up steadily to 100%. Thing is no new data is being written to the source share at all. In fact it isn't even available as a share yet so I don't get why the snapshot would be filling up. I've done this exact thing when moving data from an old server to my DSS at least 5 times before and snapshot usage never went about a couple percent when replicating. Same size share and same size snapshot.
