Zu viele offene Dateien, die von elasticsearch gewarnt wurden

Die folgenden Warnmeldungen werden fortlaufend angezeigt. Nicht sicher, was getan werden soll. Ich habe einige relevante Posts gesehen, in denen nach einer Erhöhung der Anzahl der Dateideskriptoren gefragt wurde.

Wie mache ich das gleiche?

Auch wenn ich jetzt zunehme, werde ich beim Hinzufügen neuer Indizes auf dasselbe Problem stoßen. (Derzeit arbeiten mit rund 400 Indizes, 6 Scherben und 1 Replikat). Die Anzahl der Indizes steigt tendenziell stärker an.
