Hello World!

My logs are getting flooded with following message:

> cannot compute used swap when total swap is 0 and free swap is 0

I assume it's safe to ignore since it's not recommended to have swap enabled anyways, but is there a way to not produce message in the logs in the first place?

Please advise 😉  
Thanks in advance!

Can you clarify where this is being displayed? What log?

from elasticsearch logs:

... per [Disable swapping | Elasticsearch Guide [6.8] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/setup-configuration-memory.html#setup-configuration-memory) any/all swap are disabled, however now I'm getting the above line in my elasticsearch's log over and over ...
