Logstash circuit breaking


Do anyone know how to solve this circuit breaking exception in logstash (7.10).

I have tried multiple options like

  1. To increase the jvm to 16g under /etc/logstash/jvm.options but still the same issue.
  2. Restart logstash and Elastic nodes

Is there a way where I can discard this 27.9gb data or any other better way to resolve this issue.

Thank you!

That looks like circuit breaking on the elasticsearch side.

You're going to need to take a look, but it looks to me that your elasticsearch cluster It's very high JVM usage which could mean you have very high number of indices or shards or any number of reasons.

But pretty sure that error comes from the elasticsearch side.

I too agree, this error will be coming from elastic, but JVM is 65% utilized in elastic.
