That means your node cannot keep up, not the thread pool. [Any idea what these errors mean version 2.4.2 - #5 by jasontedor](https://discuss.elastic.co/t/any-idea-what-these-errors-mean-version-2-4-2/70690/5) is a really good post on this.

It's a min of 5, but a max of half of the number of processors on the node. So a 32 core CPU will have 16 threads.  
And then the node will hold 1000 requests in it's queue before rejecting them.
