Have guys saying they aren't getting any attachments. I've increased the size limit for attachments and still have nothing hitting the phones. The connectorManager.log file is full of this message

2010-05-23 08:01:53.066 DEBUG [Thread-18] [attachments:309] [userID:] [eventID:] [objectID:] [] File already exists on SE based on hash matching. Aborting file upload

Is there anything else I should be looking at?
