I tried the reinstallation but it didn't work. Please help.

What is the /etc/logstash/jvm.options ?

#3

Lostash is running the problem is with Elasticsearch

#4

It seems like you are running with an old jvm.options file rather than the one that comes with the new version.

#5

Can you please suggest the method for me to update the jvm.options file?

#6

Sorry for typo:
/etc/elasticsearch/jvm.options

Please use the newest jvm.options if you have jvm.options.rpmnew
