What do you mean by big amount of data? Big blob fields or many rows? If latter is the reason - modify your procedure to return data in chunks and set PollWhileDataAvailable = true in adapter.

In one of my current projects I use such procedure code to get data in chunks:

DECLARE @SubsetOfChanges TABLE (ChangeID BIGINT PRIMARY KEY)

INSERT INTO @SubsetOfChanges
SELECT TOP 100 ChangeID FROM bts_DatabaseChanges WHERE Processed = 0 AND TableName = 'Producer'

SELECT p.*, changes.Operation as operation, changes.RowKey AS original_id 
FROM (SELECT * FROM bts_DatabaseChanges WHERE ChangeID IN (SELECT * FROM @SubsetOfChanges)) AS changes
JOIN [region].[dbo].crm_clsProducer p ON changes.RowKey = p.producer_id  

UPDATE bts_DatabaseChanges
SET Processed = 1
WHERE ChangeID IN (SELECT * FROM @SubsetOfChanges)

bts_DatabaseChanges is a log-table for all modifications in the DB.

Are you using the WCF LOB Adapters for this? If so, check te MaxReceivedMessageSize property on the bindings on your send receive port to increase from the default 65000 bytes.
