Elasticsearch startup is waiting and takes 7 minutes to start


I have a cluster with 2 nodes (another 1 will be added later). I made a fresh install. There is no data on ES. But on one node it takes 7 minutes to start. The system has 64GB ram but i can use with -Xms16g. If i set -Xms32g the system hangs and i wait 10 minutes, ES never start.

It is same on second node.

What can i do for this, any idea?

System Has 24 Core AMD CPU
64 GB Ram
Ubuntu 16.04 LTS
ES installed from apt repo.

Best Regards

Is there anything in the Elasticsearch logs?

Nothing on logs. After starting ES, it waits for 7-8 minutes (no logs for this time), then it is starting normally (after this point, logs are ok)

You can see after restart at 10:18, logs are started at 10:27.
