> Detecting low memory on ignite node startup
> -------------------------------------------
>
> Key: IGNITE-6003
> URL: https://issues.apache.org/jira/browse/IGNITE-6003
> Project: Ignite
> Issue Type: Improvement
> Reporter: Sergey Chugunov
> Assignee: Igor Seliverstov
> Labels: usability
> Fix For: 2.2
>
>
> h2. Motivation
> Starting from version 2.0 Ignite keeps all data in offheap area and allocates
> this area on startup based on MemoryPolicy settings.
> So several Ignite nodes started on the same machine may allocate an order of
> magnitude more memory than physically available so putting pressure on such
> cluster will cause the machine to hang.
> h2. Acceptance Criteria
> # Reliable cross-platform algorithm to detect low memory is developed.
> # Ignite node fails to start with descriptive error message when the
> algorithm detects low memory which may cause hang.
