Details:

I use pkg io-2.4.0
If i run multiple generator .xlsx file after some run we have an error.
After error is necessary close octave.
An other things that I see is that Octave generate in users temporary files a
large amount of oct-... files (every loop generate 1 file) and don't delete
after close.
Here the example that can generate the problem:


clear
more off
for j=1:(2000)
        % extract file's name
        name=dec2hex(j);
        my_path=strcat(name,'.xlsx');
        % save data into file
        data=[j,j*2,j*3];
        xlswrite(my_path,data);
  j
end

and here the problem after some loops:
j =  397
j =  398
j =  399
j =  400
j =  401
j =  402
error: fprintf: invalid stream number = -1
error: called from
