rsp.op_errno would be ENOTCONN or EINVAL if your client received an 
error from the rpc layer or if decoding of the rpc payload failed.
This situation mostly indicates that the brick set rsp.op_errno to 
EOVERFLOW. Have you checked the brick log file to determine if a 
corresponding error log message is present there?
