20 GB and 2 VCPU
3 GB per day
This is not constantly crashing, but when look at the server next day morning and it crashes due to out of memory. First we had 4 GB, then increased to 8 GB, then we increased to 20 GB. It crashes after certain number of hours.

Keep in mind that elasticsearch is will only take half of the total system memory so from its perspective it is only aware that it has 10GB of the 20GB allocated to they system(not usually recommend to exceed 64GB total). The optimize task can also lead to high memory usage without adding much benefit in return and can be disabled by setting it to 0 under Admin > System > Snapshots & Maintenance > Optimize Indexes older than.

Thank you.Will check out the recommendation and let you know if any queries.

Sounds good! We'll be here
