Any idea what is causing this error Elastic 2.4.2


#1

Some of our queries keep failing since we upgraded from 1.7.1 to 2.4.2, any idea what is causing these errors?

hi,

No guaranty, but I think it is because there is too many requests sended to the server (maybe a big bulk) and as the server is too "small" it drops some queries.


#4

It is a 20 nodes cluster AWS r3.2xlarge, plenty of computing power

There is something wrong with threadpool and queue sizes, are your bulk very large ?

Some doc about threadpool : https://www.elastic.co/guide/en/elasticsearch/reference/5.0/modules-threadpool.html

That's Marvel, so what does it say about threadpool capacity?
