[Coin-ipopt] IPOPT observations

On some of my runs, IPOPT returns with IERR = 823. I find this unusual. I
believe IERR should not be 823.
Am I right?

I tried  ifull = 1 and  iquasi = 6. With these options, the execution is
substantially slower than with  with ifull = 0 and iquasi = -3.
I am puzzled by this.
