What else are you running. Do you also have a lot if peripherals connected? Can you post more logs? I’d first try with a better power supply. I use 5.25V 3A on my rPi3 OH since I run a USB zwave, SSD, a 433LoRa module, and a fan.

In addition to the power supply, it could be that the SD card is starting to get corrupt, so you should think about replacing the SD card and moving root for example to a SSD (can be done quickly with openhabian-config)

Yep, and perhaps one of the most experienced issue.

Thank you for your answers. Have changed SD card, bought 32Gb, now works fine 2 days, will see how it affects my problem. And changed InfluxDB http setting not to log every request.

If you still haven’t gone the SSD route, it will still be just a matter of time until your new SD card will get corrupted. There are several cheap SSDs in Amazon you can use.

Could you give one Link for a cheap SSD for the PI?

Hello @vasmer, Is this issue solved ?

If answer is yes, then please help me out even I am facing same issue from past one month.

thanks in advance.

SD Card change helped. Thanks.

Thank you for response, you mean changing to 32GB SD card worked fine for you?

Consider going ZRAM to avoid this happening again soon.
