Hi all,

One of my data nodes is always running 4 "bulk" tasks, has a waiting queue of 500 (max queue limit in our settings) and millions of rejected requests.

`GET _cat/thread_pool?v`  
 ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/3/f322062ea72aad9b3052071321332cf42ef332f7.png)  
If I check the tasks running there, none of them is "long running" (according to running\_time\_in\_nanos field) thus I guess it's just a lot of small tasks arriving overwhelming my this queue.

I also notice I have some shards still INITIALIZING (they belong to very big index of around 4.2~TB) and they're indeed being processed by the same problematic node rejecting other requests. In addition, there are no errors reported by the _explain API_ for these and indeed 1 week ago it was 10 shards in this state, I measured the progress and seems that each shards takes around 15 hrs to finish and become fully assigned. Only three remain now (will probably complete in around 3-4 days) but this huge duration worries me.

```
puma.compilation.pipeline.96f19f5b-bc84-4d4b-8694-b80a293e78e4-latest 4 r INITIALIZING 10.184.95.1 data1-iil-001_data
puma.compilation.pipeline.96f19f5b-bc84-4d4b-8694-b80a293e78e4-latest 5 r INITIALIZING 10.184.95.1 data1-iil-001_data
puma.compilation.pipeline.96f19f5b-bc84-4d4b-8694-b80a293e78e4-latest 0 r INITIALIZING 10.184.95.1 data1-iil-001_data

```

The tasks related to initializations above look like this:

`GET _tasks?actions=internal:*&detailed`

    }

```

Do you know what's the best known method to be able to continue handling incoming bulk requests as the init tasks above are occupying the available slots? (which is 4 in our setup for max bulk requests)
