I was not able to find out why this error happens (repeatedly), please help me diagnose it.
I have a Raspberry Pi 3 Model B, running Raspbian Stretch Lite (2018-11-13).
- It boots successfully.
- I can access and use it without any problem.
- After 90 minutes the resources are not overused: CPU below 5%, memory 115/927M, swap 0/100M.
After a while I can not connect to it via SSH, can't access the Plex server running on it. Both the green ACT LED and the red power LED are on constantly. I have to restart it manually, after that it is working again.
Previously I have used Raspbian, not Lite. It was not producing this issue. The hardware configuration is the same, I'm using the same charger (IKEA Koppla), external HDD, and it is on the same network. The charger's specification is the following: Total output of 3.4A, 17W. Maximum output per USB port: 2.4A. Voltage USB ports: 5Vdc, https://www.ikea.com/us/en/catalog/products/60415030/.
The only new software element is the No-IP DDNS updater: https://www.noip.com/support/knowledgebase/installing-the-linux-dynamic-update-client/
Could you please tell me how I can find out what the problem might be? Thank you!

. CPU below 5%, memory 115/927M, swap 0/100M. The charger is an IKEA Koppla charger. Before the Raspbian Lite I've been using the normal Raspbian, and it did not produce these symptoms.journalctl
, but it only shows the logs of the current boot. I'll now configure it to persist the logs, so I can check back after the next freeze. Is there anything else I should check?
