RAM Unlinking

Jeder Prozess verfügt über einen Parent-Prozess welcher unteranderem die Speicherposition von den benötigten Daten managed. Diese essentiellen Presenter sind aber wie alle Prozesse in ihrer Laufzeit begrenzt und können unter Umständen auch abstürzen, was dann entweder Datenverlust oder Probleme beim Löschen des RAM`S verursacht. Es kann aber auch vorkommen, dass nur aufgrund von einer Time exception, Daten nicht mehr aktuell sind, welche eigentlich aktuell sein müssen, weil sie durch einen untergeordneten Prozess verwendet werden.  Um diese Daten zu berichtigen, macht es Sinn, denn Root Prozess mit dem Befehl sudo kill (pid) zu beenden. Bitte beachte aber, dass du den Prozess normal beendest.

 

Beispielslogs:

problem 16:52:32.483482 +0200 bird [CRIT] UNREACHABLE: We should try our best to avoid dropping fsevents

 

fehler 16:52:34.494423 +0200 bird [ERROR] Container needs deep-scan because dropped fsevents - <private>

 

fehler 16:52:36.117773 +0200 mdworker Asked to exit for Diskarb

 

 

Ich habe ganz einfach den MDWorker beendet und damit ein ähnliches Problem verursacht, wie ich es oben beschrieben habe. Die Folge darauf, war der Verlust von Daten im RAM. Durch das beenden von dem Bird Prozess konnte ich aber Speicherplatz freimachen. Weiteres Beispiel: Bei iOS 11.4 gab es ein Problem mit der Kamera. Das Live Bild wurde nicht übertragen, da ein Worker nicht funktionierte. Klicke hier um mehr zu erfahren.

Das ist passiert, als ich den mdsecurityworker beendete:
