I am using Logstash latest version 7.6.1 and I am using 4GB Ram in my machine.

When I trying to push data from Redshift to Elasticsearch using Logstash I am getting the Error:

I have increased the heap space using this command:  
LS\_HEAP\_SIZE=3072m

But still, I am getting the same error.

But the record is 10K, then logstash is working fine. same time I trying to push one lakh record the logstash throw the error.

Kindly give me any suggestions.

Thanks and Regards.
