title: How to debug failure in LSQ Subproblem
body: <p>I'm solving a dymos problem with 'SLSQP' and the SCIPY Optimizer driver and my problem fails due to 'more than 3^n iterations in LSQ subproblem'. I've been trying to understand what exactly this error means to figure out where in my model I should start debugging, but I have not found any useful resources on the topic. You all provided useful feedback on how to debug other optimizer errors, so I figured that maybe you all had some advice for this error as well.</p>
  <p>Note that my variable scaling is pretty good. Also, if I turn off the optimization variables <code>opt=False</code> and just let the optimizer converge the trajectories, the optimization completes. Then, if I enable the optimization variables <code>opt=True</code> and warm start the problem, the optimization converges as well. Although this works, I have to solve many different problems and finding a warm start solution to each problem is unrealistic. I also find it strange that the LSQ subproblem is so dependent on the initial guess.</p>
