             Summary: IoomFailureHandlerTest.testIoomErrorPdsHandling fails on 
64 core machines
                 Key: IGNITE-18169
                 URL: https://issues.apache.org/jira/browse/IGNITE-18169
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.14
            Reporter: Semyon Danilov
            Assignee: Semyon Danilov


It seems like minimal fragment size of the data region is 1 megabyte. The 
quantity of fragments is equal to concurrency level + 1 (checkpoint buffer). So 
in case if we set up region size to 10 megabytes and we have 64 cores, then by 
default we will have concurrency level 64 and instead of 10 megabytes region 
size + 10 megabytes checkpoint buffer size we will have 64 megabytes region 
size.
