Replicated this issue server side by having multiple clients connect concurrently. Exception was server side at SqlSyncProvider.BeginSession(). In Sync 2.1.

I solved this by making sure the SqlSyncProvider for the server was per client instead of static across all client connections.

Since I was replicating this via unit tests I also had this issue when client proxy reference was static, switched that to instance as well.
