matlab daq session with NI PCI-6733 - no more space in the buffer (-50410)

I am trying to generate a continuous output signal using the NI PCI-6733. i use the following code modified from a DAQ library example

devices = daq.getDevices();
s = daq.createSession('ni');
[ch1,idx1] = addAnalogOutputChannel(s,'Dev2','ao0','Voltage');
s.IsContinuous = true;
s.Rate=8000;
data=[linspace(-10,10,2500)';linspace(10,-10,2500)'];
lhq = addlistener(s,'DataRequired', ...
        @(src,event)src.queueOutputData(data));
lhe = addlistener(s,'ErrorOccurred', @myErrorFunction);
%
queueOutputData(s,data) ;
startBackground(s); 

function myErrorFunction(src,event);
    disp(getReport(event.Error));
end

A similar problem was reported on Mar 2017.

Note: the same code works much better on the NI-USB-6216
