Logstash stuck on "Will Retry with exponential backoff"

Elastic Stack Logstash
1

Hi,

We use ELK 7.5.1 version
It seems that logstash stucks on trying to make bulk requests to elastic when document size exceeded http.max_content_length:
[ERROR][logstash.outputs.elasticsearch][index_name] Encountered a retryable error. Will Retry with exponential backoff {:code=>413, :url=>"http://127.0.0.1:9200/_bulk"}

and keeps trying until it fails with out of memory:
[ERROR][org.logstash.Logstash ] java.lang.OutOfMemoryError: Java heap space

Is there limit for such retries?

From plugin manual it is unclear what about retries for 413 errors:
