Hello,

I have found the fix.

In docker-compose.yml
there is healthcheck option

     healthcheck:
       test: wget http://localhost:8545
       interval: 2s
       timeout: 5s
       retries: 30

it wgets every 2 seconds localhost:8545 to check if it is alive and this wget is downloading localhost:8545 content which is empty index.html file.

To stop creating files just remove healthcheck section or change wget to ping (but remember to install iputils-ping first)

@javahippie Possibly these are created by some http proxy? I don't think this is geth related but rather docker/nginx. Then again the others dont have it when not running geth.

I'll try some different flags and remove verbosity.

Hi waylandc,

I did not notice this, yet. Good catch, I will see what I can do.

I checked this too.

They are all empty.

It only occurs on the miners and node.
It doesn't happen on the swarm , explorer or monitor containers.

Just reporting back, that this is not forgotten. I just have no idea what's causing this. The file count increases, the longer the docker container is running, but there is only one process in the container: geth. I am trying to find some creative ways of checking the root cause of this, I even started checking geths source code, but I can't find any hints.

Appreciate that you're looking into. It's not a big deal as there's no functional defect but it's just weird to see it happening but have no idea what's causing it.

Thank you for finding this, @Adam-Kielkowski! I will add the change to the next release.

Ah yes indeed, wget is for files of http/https good spot.

Should use a custom script apparently.
