I set the search queue capacity up to 2000 a few days ago.
Why does the search active threads equal 0 when the search queue is over than 2000?
When I used kibana to check my dashboard, I got the error info below:
My ec2 environment of elasticsearch bases on the info below:
4 core cpu
The frequency of this issue above is not at a high level.
There are several visualizes in my dashboard. Each of them set an aggregation at least. I have no idea what caused this issue.
