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:
