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"

What is the DTO event status on the server side?

>Is there an limitation on the size of data been transfered?

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