Hey

I just wanted to check something in Grafana and by that found out that my influxdb addon (addon in HA) is not working anymore.

No real clue when this started … .but at least a few weeks back it was working fine

Error says: Accept error: accept tcp [::]:8086: accept4: too many open files; retrying in 1s

I temporary fixed it by running this quick and dirty hotfix script (provided by chatgpt...) under Home Assistant Operating System 17.3 to be able to run newest kernel with fix for copy fail exploit.
Maybe it help you until real fix for the addon is there :slight_smile:
Make backup. Use on your own rist :wink:
