1 means that the process has stalled, and whether this is good or bad depends on what you want. If the stall window is large, then it means that the solver is not improving, and so maybe it is time to stop.
2 means that the solver was still improving, but got stopped by a generations limit. So maybe you are tired of it running, or maybe you should increase the limit so it can improve some more.
