Hi, it seems that my Node-Red (On Raspi) is rebooting without any trigger or influence. That makes me unhappy, because it clears all chart data and history :frowning: Is there kind of a logfile showing such events and possible reasons for it ? BR G

[image] Golonder: I am using the original raspberry 3A power supply Power supplies are like houseplants, some flourish for years, others die unexpectedly. Try a different supply if possible.

[image] Golonder: no Delays, no Files, no Video But do you have any function nodes which might allocate memory, or any not-very-widely-used additional nodes? Something's eating your memory, and it's worth tracking it down.

I am using nodes for: Homematic, MQTT, Thingspeak, MSSQL, Pushover, ModBus I am using ONE Delay Node - to wait for 1 min between two HTTP Requests (turn on device, wait, turn off device) Can I see or track allocated memory ?

I'm not really familiar with the internals of Node-RED or Node.js (I spend my days in C/C++ land) so it may need input from some of the developers to help in finding the problem. [image] Golonder: Can I see or track allocated memory ? There are a couple of nodes which seem to be able to chec…

[image] ghayne: Try a different supply if possible. I don't think there is any evidence that it is rebooting, unless @Golonder has not shown us that bit of the log. @Golonder you can easily check this by running top in a terminal. That will show you how long since the last reboot. That comm…

The Raspberry is up since 20 days and 11 hours The Node-Red service is consuming 20,8% MEM and 2%CPU I am afraid that is not the issue :frowning: top - 16:42:16 up 20 days, 11:16, 2 users, load average: 0,00, 0,03, 0,01 Tasks: 140 total, 1 running, 139 sleeping, 0 stopped, 0 zombie %Cpu(s…

Also, which version of nodejs are you using on this pi? If it is 13.x as in the other thread then the first thing you should do is to install a supported version (probably 12.x). It may not be the problem but until you check there is no way of knowing.

I believe @Gawan means the power supply. If the Pi has been up for 20 days, it most likely is not the power supply

@Golonder you really should put a closing message on previous problems you have asked for help with saying what the conclusion was, as that may help others finding the thread.
