>             Fix For: 2.2

>
> h2. Motivation
> Starting from version 2.0 Ignite keeps all data offheap and allocates it 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 when 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.
