Hello Guys... I have upgraded my elasticsearch specification. Now, it has 8 Cores, 32 GB Memory, 1 TB Data. Is a must to set these settings `-Xms16g` and `-Xmx16g` ? Could i set those to be `-Xms22g` and `-Xmx22g`? Or should i create the second node with half specifications of them ? Thank you ---

Why would you need to do this? Isn't 16gb enough? ---

Thank you for replying 🙂 > Uncomitted messages deleted from journal > `Some messages were deleted from the Graylog journal before they could be written to Elasticsearch. Please verify that your Elasticsearch cluster is healthy and fast enough. ` I found it 9 hours ago in Graylog2. At least, it's pop up once a day. Before, it was pop up more than 5 times a day. That's why What's your opinion ? ---

I don't have opinion on Graylog2. I don't know it. But I'm not sure that setting the JVM to 70% will solve this in any way. ---

In your experiences, what do you think if JVM is set to 70% of memory ? Is it good ? ---

No as recommendation is at most 50% ---
