Hello,
Some of my LMs reboot unexpectedly. No error seem to happen in the Errors log. I have a KNX object that counts the restart of the LM and I can see that it restarts about 3 times a day. I have another object used for storing the value of 15-minute average CPU load, and I don't see this load growing abnormally before the unexpected restarts.
When I go into system config > Status > System logs, I can only see the system logs since the last restart, so I can't know what happened just before the restart.
Would there be any way to understand what caused the LM to reboot?

What about memory?

I don't know. I will try to write RAM usage into a KNX object at regular intervals and see if there are memory leaks happening. Thanks for the suggestion.

If you have an unexpected reboot due to the out-of-memory condition then the system won't be able save last object values. If you have multiple LMs then you can monitor one LM from another by exchanging values via KNX/IP.

I have a simulair problem with a Wiser.
I don't see any high CPU or memory.
I sent me CPU load to Influx I have every day 1 higher load of 22% at 12am because for saving energy values.
But that is not the time of the problems.
my current value's
CPU/IO: 0.18 0.08 0.02, Memory: 22%, KNX/TP: OK
I have 2 Wiser @home.
first I was testing with 2 of the same programs, but I disabled all script at the 2nd Wiser, these didn't show any problem. (1st show restarts).
Then I run the 2nd Wiser with all scripts run and both show restarts (not at the same time, but simulair).
Now I'm so far it looks like it one of the script who run for raining and or wind.
But these scripts don't create a high CPU. (as far I see)
if it is desired, I could share the 5 scripts.

Hi @all,
I also experiencing system reboots every 10-15 days but I changed nothing in the setup or scripting. Load and memory is between 0.3-0.7 and 40% memory.
How can I find the reason for the restart? Is there a log file stored somewhere? In the fault logs nothing is being raised.
Many thanks for your help!
Best regards
Steffen

Look for any errors, big amount of logs. It will be very hard to figure it out if it happens so rarely

Hi Daniel,
many thanks for your reply. I watching the memory usage and over the time it rises day by day slightly starting from 40% to 63% today within 7 days.
That's why I used the system load app to analyze the running processes regarding their memory use. And on top of it is the following resident script which is running every 60s and should use: 26880.00MB at least this is shown in the app. I have no idea why this is so memory consuming. Can you please give me your thoughts about it and ideas to improve?
Many thanks for your help!
Best Regards
Steffen

Try using scheduled script instead of resident.

Also the user lib round is not needed (no idea what the content is) but you can simply use math.round(...)

Hi Daniel,
hi Erwin,
many thanks for your reply.
I switched four resident scripts to scheduled script and in the "system load app" I saw a massive reduction in the memory consumption by 30%.
BUT when I look in the configurator app bottom right the "memory" value was unchanged. What is this value referring to? How can I look inside this value, which process/script is consuming what amount of memory?
Many thanks for your help!
Best Regards
Steffen
