In Ubuntus Kernel-Version 4.4.0-59 gibt es einen Fehler beim Umgang mit der OOM, den Sie verwenden: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842 . Sie können entweder auf einen älteren Kernel zurückgreifen oder einen neuen festen Kernel herunterladen, der dort veröffentlicht wurde.
Linux 64 Swap nicht leer, OOM beendet die Anwendung

Ich bekomme Probleme mit der OOM-Kill-Anwendung, selbst mit viel Swap
Jan 21 06:25:19[166423.248706] Free swap = 3997348kB Jan 21 06:25:19[166423.248708] Total swap = 4194300kB
Ich habe Linux ohne Swap gelesen , aber der OOM-Killer wurde ausgelöst und getestet, dass mein System durch Ausführen die Zuweisung von mehr als 4 GB ermöglicht
stress --vm 1 --vm-bytes 4096M --timeout 10s
Was könnte also der Grund für OOM sein?
