Logstash stops processing requests

Elastic Stack Logstash
1

We keep running into issues where after a while some of our logstash nodes that are reading from kafka, parsing the data, and sending to ES stop processing new requests. This is what were seeing in the logs:

{
  "inflight_count"=>1500, 
  "stalling_thread_info"=>{
    [
      "LogStash::Filters::Mutate", 
      {
        "remove_field"=>["beat", "input_type", "fields", "msg", "name", "time", "timestamp", "v"]
      }
    ]=>[
        {
          "thread_id"=>582, 
          "name"=>"[main]>worker0", 
          "current_call"=>"[...]/vendor/bundle/jruby/1.9/gems/manticore-0.6.0-java/lib/manticore/response.rb:50:in `call'"
        }, 
        {
          "thread_id"=>583, 
          "name"=>"[main]>worker1", 
          "current_call"=>"[...]/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/output_delegator.rb:128:in `pop'"
        }
      ]
    }

Is there any way to debug what's happening here?

Thanks!

We are having the same problem. Our situation is reading from redis and outputting to logstash. But ultimately we get the same result.

Did you find a solution to this?
