Do you know what the "'(ionclean)" process is and why it's using 100% cpu time ? I have no other information with htop
@Carnet If Linux, try ls -l /proc/<ionclean's PID>/exe, then feed the link target into your package manager's "get package owning file" feature (most of them have one, the man page or a Web search should tell you how).
@Carnet If it's an interpreter script (e.g. /proc/<PID>/exe points to /usr/bin/python3), try cat /proc/<PID>/cmdline; the script's path should be the first argument.
