Suddenly, my ElasticSearch works very slow. When I do a query, I get the following:

I know about the security license, but my license was expired some months ago. Any idea?

What makes you think that this is the culprit? The above is not coming from a query, but from a watch execution.

Also can you explain in more detail what `works very slow` means? Is indexing slow? Is searching slow?

Please take some more time to properly write up an issue, especially about the changed behaviour.

Thank you!
