Sink successful while source is still queued

[jonesb321]

Looking for any guidance to this issue.  

The Sink is already successful, but the data flow activities used by the sink are queued. As a result, the data isn't committed in the destination table and I keep getting timeouts as a result.

I changed the SQL Based source to Read Committed (was Read Uncommitted), and it yielded the same result.

So, this is a bit misleading as the status shows success, but the sink has not completed/committed the batched changes. Due to performance reasons, it was taking 2.5 hours to insert the 720k+ records, but was still indicating success. Seems the status should have remained "in progress" until the sink was complete.
