Jahresrückblick 2025 – unser neuer Blogbeitrag ist online! ✨

[Codierknecht]

@shellyrulestheworld sagte in Raspberry Absturz alle 3 Tage:

admin.0 gibt es nicht mehr.
Kann das ein Problem sein?

Nö - in dem Fall eher nicht.

[shellyrulestheworld]

@apollon77 jetzt kommt ne doofe Frage: was möchtest du haben und wie lade ich es am besten herunter?

[Thomas Braun]

@shellyrulestheworld

CodeTags verwenden, keine Screenshots.

less -R /var/log/syslog

[shellyrulestheworld]

@thomas-braun da steht zu viel drin ... das hier in Codetags würde den Rahmen sprengen...
Beispiel:

@thomas-braun reicht die Zeit oder noch mehr davor / danach ?

[Gaspode]

Dazu hat @apollon77 schon vor längerer Zeit in einem anderen Thread was geschrieben:

@apollon77 said in Iobroker stuerzt immer wieder mal ab:

Wenn oom_reaper bzw oom_killer im
Syslog stehen dann geht dir der Speicher aus und der Kernel schießt Prozesse ab. Also ramnutzung wird dein Problem sein. Es läuft mehr als du ram hast.

Es ist also wohl so, wie er oben bereits vermutet hat:

Könnte Grenzwertig sein.

Er läuft jetzt ja auch erst 14 Stunden, und nach drei Tagen kommt es zu dem Problem. In der Zischenzeit kann viel passieren, die RAM Auslastung ist ja nur eine Momentaufnahme. Evtl. hast du auch einen Prozess, der allokierten Speicher nicht mehr sauber freigibt.

Ich würde mir an deiner Stelle mal regelmäßig die RAM Auslastung ansehen, so etwa alle 4 bis 6 Stunden, ob ein Trend erkennbar ist.

Hier zur Hintergrundinfo (was passenderes habe ich auf die Schnelle nicht gefunden, aber das Prinzip wird verständlich erklärt):

@shellyrulestheworld
Prüf mal ob der v4l2 Kram da erforderlich ist. Kamera im Einsatz? Die scheint jedenfalls nicht korrekt installiert zu sein.

[shellyrulestheworld]

@thomas-braun ich habe eine Netzwerkkamera im Einsatz. Von dem her brauch ich diese Kamera nicht. Deshalb hab ich die montion.conf angepasst und die Kamera "kommentiert" (Zeile 18)
Müsste passen, oder?

  GNU nano 5.4                       motion.conf
setup_mode off

# File to store the process ID.
; pid_file value

# File to write logs messages into.  If not defined stderr and syslog is used.
; log_file value

# Level of log messages [1..9] (EMG, ALR, CRT, ERR, WRN, NTC, INF, DBG, ALL).
log_level 6

# Target directory for pictures, snapshots and movies
; target_dir value

# Video device (e.g. /dev/video0) to be used for capturing.
;video_device /dev/video0

# Parameters to control video device.  See motion_guide.html
; video_params value

[Thomas Braun]

@shellyrulestheworld

Auskommentiert wird mit dem 'Gartenzaun'/ der Raute. Wie z. B. in Zeile 5 zusehen.

[shellyrulestheworld]

@thomas-braun wie kann man denn ans Ende der syslog springen? Beim scrollen wird man ja wahnsinnig ;-)

und ich habe mal nicht genutzte Instanzen deinstalliert bzw. teilweise pausiert.

[Thomas Braun]

Ja Danke, in "meinem" Link wird das Prinzip von OOM-Killer erklärt, deshalb hatte ich den gewählt.

Auf jeden Fall ist es ein deutlicher Hinweis auf (zu) wenig Memory, wenn OOM-Killer zuschlägt, soweit ich das verstehe.

Ja, der OOM-Killer haut zunächst für das Kernsystem unwesentliche Prozesse ins Nirvana.

[shellyrulestheworld]

@thomas-braun
hab ";" durch "#" ersetzt. Aber leider scheint Motion immer noch nach der Kamera zu suchen. Hat jemand noch einen Tipp bzgl. Motion ? ;-)

Ich kenne motion nicht.

@Gaspode

Steht auch drin:

Warning signs of a genuine low memory situation that you may want to look into:

• available memory (or "free + buffers/cache") is close to zero
• swap used increases or fluctuates
• dmesg | grep oom-killer shows the OutOfMemory-killer at work
