You are most likely running into access violations or some other
error. You should see the following message with any DTO error:

"DTO completion ERR: status %d, op %s, vendor_err 0x%x - %s\n"
I didn't see this error message.
What is the DTO event status on the server side?

12734: ERROR: DTO event status :DAT_SUCCESS DAT_RESOURCE_TEP
Is there an limitation on the size of data been transfered?

based on the HCA max_msg_sz, usually 2GBytes (ibv_devinfo -v).
