Node stops running

post by Ansuz4u on Apr 17, 2021

I start my node but after a short time its stops and i have to restart it. I am running on a Pi 4B with Raspian Buster. I will be checking the status and i notice the node has stopped running. I have it running on a dedicated ip through my router. Sometimes it’s hours other times its less than 30 minutes.

Cannot contact Algorand node: Get “ http://127.0.0.1:8080/v2/status”: read tcp 127.0.0.1:42996->127.0.0.1:8080: read: connection reset by peer

Can you post the end of the log data/node.log?

Can you check RAM use?

Can you check algod was not killed because of OOM (do dmesg -T | egrep -i 'killed process')?

What command should i use to get the node.log file open so I can copy and paste it for you? I tried opening the file in the text editor but it does not work

Ram Use

total used free shared buff/cache available Mem: 3827 358 2253 106 1215 3236 Swap: 99 85 14

To show the end of node.log, run tail -n 25 data/node.log.

You can paste the result there between triple backquotes ```…``` to have better formatting.

But it looks like the issue is that you run out of RAM (OOM).

Can you add a bit of swap ( https://raspberrypi.stackexchange.com/a/1605)?

E.g., 4GB of swap?

Also are you running many processes beyond Algorand?
