Ilya Shishkov updated IGNITE-21637:
-----------------------------------
Description:
Ignite Node can fail with segmentation violation in case if eviction policy is
used and large amount of allocated pages because of integer overflow.
One of the problematic places [1] where we can ge incorrect value when
{{trackingIdx}} is more than {{Integer.MAX_VALUE / 8}}:
{{trackingArrPtr (long) + trackingIdx (int) * 8}}.
