YaCy: CPU 95% on all cores

There are no crawls running. What could be making YaCy use so much of the CPU for so long (hours and hours)?

If the computer is shut down and YaCy restarted, the same situation occurs again.

A wild guess is that it is "Postprocessing Progress
busy:collecting ".

Does anybody have any suggestions?

running on windows? Most likely it’s the windows updater.
If not, start w/o YaCy. If sure its’YaCy - look into yacy00.txt
