SL Reboots

[AlexLV]

Hi, 

strange problem appears with SL approx from 28.08.23. 

Device not response, but periodically is possible to connect. Memory is used till 96%, then device hung up, then reboot and again the same. SD Card is used only 18%. 

Also should such info be shown in log:
   

What it could be?

If the device runs out of memory it will reboot automatically. Nothing can be done about this.
96% memory usage is not normal, usually it is around 20%-30%. How many trends do you have? Also check the database size inside a backup.

Hi. I am user of SL machine, about wich Alex asked a question.

I am running 29 trends an my backup file is 8,3 Mb.

Why do i see this log: Sep 19 05:37:15 spaceLYnk daemon.info avahi-daemon[1151]: Found user 'nobody' (UID 65534) and group 'nogroup'?

avahi-daemon is responsible for mDNS. There's nothing wrong with this log entry.

What is the total size of all trends?

Log size is 1,99 MB.
When this problem started to happen, cleaned out logs and before cleaning it was close to 10 MB.

Install Processes app, sort table by %VSZ in descending mode and drop a screenshot here.

It looks like you have a loop in event scripts where one script executes another and at some point the system runs out of memory due to having too many processes. Check that event scripts don't use long os.sleep() calls unless the script execution mode is set to first or last instance.

Thank you for your answer, it helped me get to the problem.  
We had multiple timers running for 80 min because of an human error, and when i changed it back to 4 min, as it should be, everithing is working perfectly.
