Looks like it is trying to run TLP, which is still somewhat experimental. Set forceDLP=1 in yafu.ini or use forceDLP on command line. I should set the crossover point much higher.

Super slow SIQS job

You need to hit Ctrl+C twice somewhat rapidly. If it doesn't detect a second Ctrl+C soon enough it will resume.

It works fine with 2.02. I was using 2.0 for that run. Sorry for the trouble.
