Seit einiger Zeit habe ich ein Problem, bei dem wichtige Systemprozesse von LowmemoryKiller / OOM gewaltsam beendet wurden.
Nach der Hilfe habe ich vor ein paar Tagen eine 500-MB-Auslagerungsdatei hinzugefügt, um den Speicherdruck und Low-Memkiller-Trigger zu reduzieren ( Thread mit Details hier ). Die Ausgabe von freezeigte zusätzliche 500 MB Speicherplatz, was meiner Meinung nach ausreicht, um zu verhindern, dass ein Problem mit geringem Arbeitsspeicher die Systemprozesse zwangsweise beendet.
Aber es hat nicht geholfen. Aus heiterem Himmel bekam ich plötzlich wieder ein ziemlich bösartiges "Alles wurde von LowMemKiller getötet", mit ungefähr 6 Core-Dump-Dateien, die in nur 100 Sekunden erstellt wurden, gefolgt von einem Absturz des Benutzerraums, und das Kernel-Protokoll (dmesg) deutet darauf hin Speicherprobleme waren das einzige gemeldete Problem, obwohl diesmal eine große Menge Swap verfügbar war und vom System erkannt wurde (siehe freeunten).
Hier ist der relevante Teil von dmesg >dmesg.txtkurz nach dem initNeustart von Userspace. Im ersten Teil des Protokolls vergehen lange Zeiträume von mehreren Sekunden, in denen nichts Neues passiert. Wenn der Benutzerraum während der 100 Sekunden bei 2105-2208 abgeschaltet wird, gibt es vorher nichts und keinen Hinweis auf einen Grund.

Allerdings swapwar aktiv und es ist nicht klar, was passiert. Ausgabe von freeunmittelbar nach Wiederherstellung des Userspace:
total used free shared buffers
Mem: 903272 879320 23952 0 1844
-/+ buffers: 877476 25796
Swap: 687060 19024 668036
Keine Ahnung was los ist. Exotische Vermutungen FWIW: (1) Swap ist verfügbar und aktiviert, wurde jedoch aus irgendeinem Grund in dem Fall nicht verwendet, in dem der Arbeitsspeicher knapp wurde. (2) Ein Prozess entschied plötzlich, dass er ungefähr 1 GB RAM benötigte und im Vordergrund ausgeführt werden musste, was zu fehlgeschlagenen Versuchen führte, wichtige Systemprozesse mit niedrigerer Priorität auszutauschen. (3) Unvorhersehbarer dramatischer Speicherverlust.
Ich weiß nicht, wohin ich von hier aus gehen soll.
Das Telefon läuft mit CyanogenMod 11 M6 und hat 1 GB RAM, und die Apps sind ziemlich Standard - Firefox, WhatsApp, nichts Ungewöhnliches, keine seltsamen "Optimierungen", keine seltsamen Modding-Apps.
Wie kann ich dieses Problem beheben?
UPDATE Mir wurde klar, dass ich die relevanten Core-Dumps finden konnte. /data/tombstonesenthält 6 Speicherauszüge, die alle während des Zeitraums von 100 Sekunden erstellt wurden, in dem Lowmemorykiller-Ausbrüche auftraten dmesg. Die Core-Dump-Dateien zeigen meistens Segmentierungsfehler (SIGSEGV), aber der Besitzprozess ist in jedem Dump unterschiedlich:

Frühere Core-Dumps im selben Ordner waren genauso vielfältig - Thread-Besitzer zählten zum Beispiel "Galerie". Einige zeigten SIGABRT anstelle von SIGSEGV. Darüber hinaus braucht es hier wohl Entwicklerkompetenzen. Was kann ich tun, um die Ursache aufzuspüren?

low memory?Probleme und FC's auf meinem HTC. Ich bin nicht besonders gut darin, mir Protokolle anzuschauen, aber Ihre Gründlichkeit hat mir geholfen, es ein bisschen besser zu verstehen (und ich musste keinen Kurs belegen oder ein langes Buch lesen… lol). Vielen Dank.Antworten:
Android verfügt über ein integriertes RAM-Verwaltungssystem, das bei seiner Arbeit ziemlich gut ist. Ram-Management-Anwendungen sind bekannt dafür, dass sie nur Schlangenöl sind. Im schlimmsten Fall tatsächlich schädlich für die laufenden Prozesse. Ich würde postulieren, dass diese Memory-Killer-App die Hauptursache für Ihre Probleme ist. Lösung. Flashen Sie Ihr Gerät zurück. Löschen Sie die LowMemory-App und sehen Sie, wie sie sich verhält

Ich verstehe nicht ganz, ob das Problem plötzlich auftritt oder ob es nur bei CM11 auftritt oder nicht. Meine erste Empfehlung wäre, die Werkseinstellungen zurückzusetzen und mit einer Auswahl von Apps zu starten, weniger aus dem Play Store zu installieren und zu prüfen, ob ein Problem auftritt. Wenn dies der Fall ist, führt CM einige wirklich aggressive Werte für LMK aus (aktualisieren Sie möglicherweise auf etwas Neueres oder erstellen Sie das ROM mit geänderten Werten). Wenn dies nicht bedeutet, dass eine Ihrer Apps Android meldet, benötigt sie RAM und Android (möglicherweise aufgrund von schlecht eingestellten Dalvik- oder Hwui-Heaps oder Kernel-LMK-Werten) und startet einfach den Massenmord an Prozessen.

Wenn diese App zum Zeitpunkt des Kaufs nicht auf Ihrem Telefon vorhanden war, sondern erst später installiert wurde, ist es möglich, dass es sich bei der entsprechenden App um Malware handelt. Ich würde vorschlagen, direkt zu Verizon zu gehen und sie herausfinden zu lassen, was los ist. Es mag viel kosten, aber wenn es repariert werden kann, ist es es höchstwahrscheinlich wert.
