Hi, I tried to configure threadpool in elasticsearch.yml for ES 0.17.6, but it fails to start up. Here is my setting: threadpool: search: type: blocking min: 5 max: 20 wait\_time: 30s keep\_alive: 90s index: type: blocking min: 3 max: 10 wait\_time: 30s keep\_alive: 90s When try to it start up, ES logged "creating thread\_pool" over 100,000 times like the following: [2011-09-10 16:08:27,500][DEBUG][ threadpool ] [staging-ss5] creating thread\_pool [cached], type [cached], keep\_alive [30s] [2011-09-10 16:08:27,500][DEBUG][threadpool] [staging-ss5] creating thread\_pool [index], type [blocking], min [3], size [10], keep\_alive [1.5m], wait\_time [30s] [2011-09-10 16:08:27,500][DEBUG][threadpool] [staging-ss5] creating thread\_pool [cached], type [cached], keep\_alive [30s] [2011-09-10 16:08:27,500][DEBUG][threadpool] [staging-ss5] creating thread\_pool [index], type [blocking], min [3], size [10], keep\_alive [1.5m], wait\_time [30s] Eventually it logged error: [2011-09-10 16:09:04,753][ERROR][bootstrap] {elasticsearch/0.17.6}: Initialization Failed ... 1. IllegalStateException[This is a proxy used to support circular references involving constructors. The object we're proxying is not constructed yet. Please wait until after injection has completed to use this object.]2) IllegalArgumentException[null] Am I missing something in the config? Thanks! Huy ---

It looks like the issue is with "blocking" type. Changing type to "fixed" it worked fine. The following setting works: threadpool: index: type: fixed size: 50 search: type: fixed size: 500 Huy On Sep 10, 12:21 pm, Huy Le [hu...@leveragingit.com](mailto:hu...@leveragingit.com) wrote: > Hi, > > I tried to configure threadpool in elasticsearch.yml for ES 0.17.6, but it > fails to start up.

heya, yea, its a bug, fixed here: [Thread Pool: Blocking thread pool type configuration fails · Issue #1321 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/1321). Will be part of 0.17.7, which will have more options to thread pool config. Once 0.17.7 is out, I will also properly document all the different thread pool options and what they mean.
