I am trying to run a Logstash service ingesting the data returning from curl command. Somehow, the Logstash is failing saying with the following warnings and errors.

I tried running the Logstash with option - LS\_HEAP\_SIZE=10g , but still it is failing. I think I am missing some setting here. Someone, please correct me.

/etc/logstash/jvm.options

I changed the value here and it worked.
