Timidity läuft und beansprucht einen Kern meiner CPU

Question

Zweimal (mit etwas Zeit dazwischen, ein paar Wochen, glaube ich) ist Timidity aus dem Nichts gestartet, wenn ich meinen Computer aus dem Ruhezustand hochfahre. Es beansprucht die gesamte Rechenleistung eines meiner Kerne und läuft jetzt seit etwa 5 bis 10 Minuten, und ich würde gerne wissen, warum dieser Prozess gestartet wird.

Beim Ausführen pstreewird der Prozess als direkter Nachkomme von angezeigt, systemddaher nehme ich an, systemddass er für den Start verantwortlich ist timidity, aber ich weiß nicht, wie ich nach der Konfiguration suchen soll, die gestartet wurde timidity.

Wenn ich straceden Prozess ausführe, erhalte ich Folgendes:

Die durch diesen Prozess geöffneten Dateien sind:

/dev/null
/dev/snd/timer
/dev/snd/pcmC0D0p
/dev/snd/controlC0
/dev/snd/seq

Die ausgeführte Befehlszeile lautet:

/usr/bin/timidity-Os-iAD

Diese letzten 3 Informationen sind entnommen aus /proc/$PID/.

Daher frage ich, wie ich herausfinden kann, warum timidityausgeführt wird (auf das Problem, warum es alle Kerne beansprucht, werde ich mich später näher eingehen).

Answer 1

 cat /run/systemd/generator.late/timidity.service
# Automatically generated by systemd-sysv-generator

[Unit]
SourcePath=/etc/init.d/timidity
Description=LSB: start and stop timidity

Die systemd-Unit wird dynamisch von systemd generiert. Um den Start zu verhindern, kann man chkconfigden Link verwenden oder löschen. /etc/rc2.d/S01timidityIch würde das bevorzugen.chkconfig --del timidity
