odeFunction, many variables

Does odeFunction(expr, vars) have a maximum number of symbolic variables/equations?

I ask because I am working with a rather large (total = N^3) number of ODEs. When N=10 or less, my code runs. When N=11, I get

    Error using mupadengine/feval (line 187)
    Duplicate variables specified in second argument.
    
    Error in sym/odeFunction (line 118)
      A = feval(symengine, 'daetools::odeFunction', expr, vars, params{:});
    
    Error in MAIN (line 212)
        ode_fun = odeFunction(x_dot,x);

when calling odeFunction.

I found a different way to set up my ODEs so I don't need symbolic variables and therefore odeFunction (thus, avoiding the problem), but I am still curious about this.

I have brought this issue to the notice of our developers. They will investigate the matter further.
