LowMemoryKiller tue de nombreuses applications système et force la mort de l'espace utilisateur, mais "gratuit" dit qu'il y a beaucoup de mémoire

14

Pendant un certain temps, j'ai eu un problème, où des processus système cruciaux étaient tués de force par LowmemoryKiller / OOM.

Suite à l'aide, j'ai ajouté un fichier d'échange de 500 Mo fonctionnant en mode natif il y a quelques jours pour essayer de réduire la pression mémoire et les déclencheurs lowmemkiller ( thread avec les détails ici ). La sortie de a freemontré un espace supplémentaire de 500 Mo, ce qui, selon moi, était suffisant pour empêcher tout problème de mémoire faible de tuer de force les processus système.

Mais cela n'a pas aidé. Tout à coup, j'ai soudainement reçu un "tout a été tué par LowMemKiller" tout à fait vicieux, avec environ 6 fichiers de vidage de mémoire créés en seulement 100 secondes, suivis d'un plantage de l'espace utilisateur, et le journal du noyau (dmesg) suggère que faible les problèmes de mémoire étaient le seul problème signalé, même si cette fois une grande quantité de swap était disponible et reconnue par le système (voir freeci - dessous).

Voici la partie pertinente de l' espace utilisateur redémarré dmesg >dmesg.txtpeu après init. Dans la première partie du journal, de longues périodes de plusieurs secondes passent où rien de nouveau ne se passe; lorsque l'espace utilisateur est tué pendant les 100 secondes à 2105-2208, il n'y a rien à l'avance et aucune indication de cause.

Cependant swapétait actif et ce n'est pas clair ce qui se passe. Sortie freeimmédiatement après la restauration de l'espace utilisateur:

             total         used         free       shared      buffers
Mem:        903272       879320        23952            0         1844

Swap:       687060        19024       668036

Aucune idée de ce qui se passe. Exotic devine FWIW: (1) Swap est disponible et activé, mais pour une raison quelconque, n'a pas été utilisé dans l'événement, lorsque la mémoire est devenue faible; (2) certains processus ont soudainement décidé qu'ils avaient besoin d'environ 1 Go de RAM et de s'exécuter au premier plan, ce qui a échoué à échanger des processus système cruciaux mais de priorité inférieure; (3) Fuite de mémoire dramatique imprévisible.

Je ne sais pas où aller d'ici.

Le téléphone fonctionne sous CyanogenMod 11 M6 enraciné et a 1 Go de RAM, et les applications sont assez standard - Firefox, WhatsApp, rien d'inhabituel, pas d'étrange "peaufinage", pas d'étranges applications de modding.

Comment puis-je résoudre ce problème?

MISE À JOUR J'ai réalisé que je pouvais trouver les vidages mémoire appropriés. /data/tombstonescontient 6 vidages mémoire qui ont tous été créés au cours de la période de 100 secondes pendant laquelle se sont produites des explosions à faible niveau de mémoire dmesg. Les fichiers de vidage principaux affichent principalement des erreurs de segmentation (SIGSEGV) mais le processus de possession est différent dans chaque vidage:

2014-12-02 12:27:33 name: Thread-20  (lbesec.loader) signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr b3baed71
2014-12-02 12:27:11 name: zygote  (zygote) signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 5dd8ce64
2014-12-02 12:27:05 name: zygote  (zygote) signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 5dd86e64
2014-12-02 12:26:57 name: zygote  (zygote) signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 5dc03e64
2014-12-02 12:26:47 name: system_server  (system_server) signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr deadf00c
2014-12-02 12:26:46 name: Binder_4  (com.android.systemui) signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr cfc08b9a

Les anciens vidages de mémoire dans le même dossier étaient tout aussi divers - les propriétaires de threads incluaient par exemple "galerie". Certains ont montré SIGABRT au lieu de SIGSEGV. Au-delà, ici, il faut probablement des compétences de développeur. Que puis-je faire pour retrouver la cause?

+1 pour une question bien formulée. Excellente présentation. J'ai des low memory?problèmes et des FC sur mon HTC. Je ne suis pas très doué pour regarder les journaux, mais votre minutie m'a aidé à mieux le comprendre (et je n'ai pas eu besoin de suivre un cours ou de lire un long livre… lol). Merci.

Le téléphone fonctionne-t-il lentement? Le travail de LowMemoryKiller est de libérer de la mémoire lorsque d'autres applications en ont besoin, et il le fait en libérant de la mémoire à partir d'applications qui n'en ont actuellement pas besoin. Voici la documentation de Google sur LowMemoryKiller .

Je pense qu'il est possible que l'arrêt de CyanogenMod ait quelque chose à voir avec cela. J'ai remarqué un comportement étrange de mon système depuis qu'ils ont fermé leur serveur Web, comme l'ouverture de la page des paramètres de données avancés faisant planter l'application des paramètres. Encore une fois, c'est une supposition totale.

Android a un système de gestion de RAM intégré qui est assez bon dans son travail. Les applications de gestion des béliers sont réputées pour être un peu plus que l'huile de serpent. Au pire, nuisible à ses processus en cours. Je postulerais que cette application tueur de mémoire est la cause première de vos problèmes. Solution. Reflasher votre appareil supprimer l'application lowmemory et voir comment elle se comporte

-1. Vous vouliez bien, mais votre réponse est erronée. LowMemoryKiller est une partie intégrée d'Android, pas une application de gestion de RAM tierce. Veuillez voir ici afin d'afficher le code lowmemorykiller.c du noyau android-4.4. (Remarque: le noyau Android 4.4 est complètement sans lien avec Android 4.4 « KitKat » périphériques KitKat utilisent un noyau beaucoup plus..)

Je ne comprends pas très bien si le problème survient soudainement ou s'il se produit avec CM11 ou non. Ma première recommandation serait de réinitialiser les paramètres d'usine et de fonctionner avec une sélection squelette d'applications, moins vous installez mieux depuis Play Store et voyez si un problème se produit. Si c'est le cas, CM exécute des valeurs vraiment agressives pour LMK (peut-être mettre à jour vers quelque chose de plus récent ou construire la rom avec des valeurs modifiées). Si cela ne signifie pas que l'une de vos applications indique à Android qu'elle a besoin de RAM et d'Android (peut-être en raison de tas de dalvik ou de hwui mal définis ou de valeurs lmk du noyau) panique et commence juste le meurtre de masse des processus.

Si cette application n'était pas sur votre téléphone lorsque vous l'avez achetée, mais qu'elle a été installée par la suite, il est possible que l'application qui fait cela soit un malware. Je suggère d'aller directement à Verizon et de leur demander de comprendre ce qui se passe. Cela peut coûter cher, mais s'il peut être corrigé, cela en vaut probablement la peine.

Voir le commentaire en réponse de @unforgettableid. Lowmemorykiller est une partie intégrée du système Android. Ce n'est pas une application, encore moins un malware.

De plus, si vous avez flashé CyanogenMod sur votre téléphone, il est très peu probable que le transporteur y soit pour quelque chose. Il est possible que le fabricant répare le téléphone, même hors garantie, comme pourrait le faire un «magasin de réparation de téléphones portables». Les moteurs de recherche ou les forums CyanogenMod peuvent également être utiles. Si vous pouvez faire fonctionner le téléphone assez longtemps, vous pourrez peut-être flasher une version plus récente ou restaurer votre téléphone avec l'original que vous avez sauvegardé avant de flasher. Un nouveau «téléphone zéro dollar» de votre opérateur va coûter le moins cher et vous avez la valeur de la leçon apprise.
