HW ausreichend?

[mosa]

seit einigen Tagen plagen mich plötzliche SystemBlockaden, da bleibt nur noch OFF/ON.
Sieht aus wie ein Harddisk-kleber?
was meint ihr dazu:

Aufgabe dieses Rechners, VSFTP-Server.
Ist dies HW-Zusammenstellung zu minimal?
PS: top wurde bei aktiven FTP-Transfer aufgenommen.
Danke

Ich kann (auf dem top Auschnitt) kein Problem erkennen. Steht nach einem Absturz etwas im syslog?

Steht nach einem Absturz etwas im syslog?

Nein, leider nichts, trägt sogar den Zeitstempfel von gestern
hat also nichts mit der geringen Memory zu tun?
vermute mal das die Platte hinüber ist, wie kann ich dies prüfen?

[OppaErich]

Müsste ja eigentlich lost&found dann besiedelt werden. Bei nicht reproduzierbarem denke ich immer zuerst an Netzteil und Ram.

Wie kommst Du da nur drauf?
In dieser Top Ausgabe ist wirklich nichts außergewöhnliches zu erkennen, und auf bestimmte Komponenten weist da erst recht nichts hin.

Steht denn wirklich nichts im syslog/dmesg?
Festplatte mit smartctl begutachten (Forensuche), Speicher mit memtest86+ testen.

sieht schlech aus,?

sind verdächtig. Aber ganze Sektoren wurden noch nicht ausgelagert.
Gerade die UDMA Fehler schlagen sich immer in den Kernel Meldungen nieder (dmesg, syslog).
Wäre es eine Desktopplatte, könnte man die Kabel/Stecker überprüfen, bei einem Notebook ist das problematischer.
Ob diese Fehler etwas mit eventuellen Freezes zu tun haben, lässt sich nicht genau sagen.
