CNNScoreVariants, too much threads

Hi,

in the BestPractice workflows you advise to use HaplotypeCaller with the "-XX:GCTimeLimit=50" and "-X:GCHeapFreeLimit=10" java options.

Is there something similar for CNNScoreVariants? I tried to use several java options with different values to limit threads but it is quite impossible. Without any option I have 116 threads, running only one command, with 5 java options I can limit them to 95 ... still too much! What should I limit here?

Many thanks
