Cerbo random reboots - multiple times daily

[NFBR]

My Cerbo reboots randomly multiple times daily when Large Image is installed

Tests done

• Standard Image - no reboot
• 3 different Cerbo units, v1 and v2 - random reboots
• 48V vs 12V supply - random reboots
• Extra fan cooling - random reboots
• Factory reset - random reboots
• USB Hub changed 3 times - random reboots
• MicroSD - removed / changed - random reboots

Large Image - no config / modules - default image

Many topics on this subject worth a look.
Check you don’t have reboot on comms loss enabled in settings.
After that you will need to dig around in logs to find out more, most of this is discussed in existing topics already.

You have a lot of devices and multiple inverters, that won’t be helping and might be pushing the system resources.

@NFBR

when Large Image is installed

And with the small image you have no random reboots?

[NFBR]

Correct

[NFBR]

VRM loss reboot is not enabled
I can’t find anything in logs, but maybe haven’t dug deep enough
I have been through all the threads - none seem to align.
It didn’t used to, so it’s within the last 6mths that it’s started - leading me to think it’s OS version related

[nickdb (Nick)]

There is an OS log you can get to via ssh.
If it is a watchdog restarting it, it will be in there.
But if its stable on the small image then it is resource related, since you haven’t configured anything like nodered or signalk to start.
Versions get heavier as they get newer, so pretty easy to cross a threshold that you were just beneath previously.

There is a custom widget on VRM advanced for the GX - dbus roundtrip time. If it is high there is a resource issue. It will be stored historically on vrm.

i had the same problem, tried many things

i found this thread:

Unwanted Reboots

I found, that the gui-v1 service is occasionally consuming quite some cpu, despite i’m no longer using it. svc -d /service/start-gui stops it, but be aware that this also terminates the vnc service, used to display the remote-console (for either version) through vrm. Then, you can only access the local ui remotely when you have a vpn connection and can access the device ip directly. Other than that, do a df -h and check the remaining disk space on the root partition. With the large image, th…

i set watchdog triggers higher - since then - problem gone

Dou have the GUI locally open on your PC?

This consumes a lot of Resources (even if it´s just an open Tab in the Browser background)

Also worth disabling this:

Only the local screen

The large image uses more resources.

Have you enable Node Red and ““Access MQTT””?

If you do not used them disable the services

There is a watchdog timer when you use high resources =>system reboots.

How to check watchdog reboots.

Login ssh

cd /data/log

grep “shutting down” *

(I have problems …….too……)

error- daemon.err watchdog[469]: loadavg 8 7 4 is higher than the given threshold 0 6 6!

How check average

command uptime

For trouble shouting there is a process file (last reboot)

/data/log/watchdog_processlist.txt

More info how to change config (is not the solution…)

Cerbo GX still rebooting multiple times a day even after the firmware update...

Example

[kr0815]

this is my uptime log

I changed the watchdog config end of last month

(config has to be changed after each update)

[NFBR]

Tracked it CPU and watchdog - disabled animations solved it.
