Hin und wieder benutzt mein Ubuntu die Festplatte wie verrückt, und 3 Minuten lang kann ich weder die Maus bewegen noch auf eine Konsole zugreifen, selbst STRG-ALT-RÜCKSEITE und STRG-ALT-F1 tun nichts.
Dies ist normalerweise der Fall, wenn Sie eine Aktion ausführen (Öffnen eines neuen Browser-Tabs, Starten von Eclipse usw.).
Ich denke, dass zu dieser Zeit mein Ubuntu ohne Grund wie verrückt zu tauschen beginnt.
Es passiert mehr, wenn ich OpenOffice + Eclipse + Firefox geöffnet habe, aber manchmal passiert es auch, wenn nur sehr einfache Apps geöffnet sind.
Ich habe iotop verwendet, um die Festplattenaktivität während eines dieser Einfrierungen aufzuzeichnen. Dieses Mal hatte ich nur Chrome, Gnome-Terminal, gedit geöffnet. Ich hatte mit iotop angefangen sudo nice -20 sudo iotop -tbod10 > ~/iotop.log
. Es soll alle 10 Sekunden in das Protokoll schreiben, aber während des Einfrierens konnte es nichts schreiben. Das Protokoll kurz vor dem Einfrieren (09:42:23) zeigt kswapd
jedoch wahrscheinlich den Schuldigen an 12.26 M/s

Ich habe viel mehr RAM, als ich tatsächlich brauche, also ist diese verrückte Verrücktheit verwirrend.
Wie kann ich diese Einfrierungen stoppen?
