["Andrey Gura (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-6892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrey Gura updated IGNITE-6892:
--------------------------------
    Description: 
{{java.lang.OutOfMemoryError}} should be handled accordingly to provided failure handle. 

There are at least 3 types of places where OOM can be catched:

1. Crtitical workers that listed in IEP-14. In this case we just handle failures as {{CRITICAL _WORKER_TERMINATED}}.
2. Other threads. We should consider uncaught or default exception handlers for such treads.
3. {{IgniteUtils.convertException()}} and {{IgniteUtils.convertExceptionNoWrap}} methods that should invoke failure handler in case of {{OutOfMemoryError}}.

Some memory should be reserved at node start to increase chances of OOM handling.

  was:
In case of any OOM node should be stopped anyway, what we can provide is user callback, something like 'beforeNodeStop'.

Some memory should be reserved at node start to increase chances of OOM handling.
