Alexey Goncharuk updated IGNITE-4959:
-------------------------------------
Fix Version/s: (was: 2.3)
2.4
> Possible slight memory leak in free list
> ----------------------------------------
>
> Key: IGNITE-4959
> URL: https://issues.apache.org/jira/browse/IGNITE-4959
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.0
> Reporter: Ivan Rakov
> Assignee: Alexey Goncharuk
> Fix For: 2.4
>
>
> To reproduce, run PageEvictionMultinodeTest (any eviction mode), set ENTRIES
> to Integer.MAX_VALUE.
> Observations:
> 1) After a few minutes of test running, number of allocated pages looks like
> a constant (a bit more than eviciton threshold, 90% by default). This is
> expected behaviour with enabled page eviction.
> 2) More precise measurement shows that there's slow linear growth of
> allocated pages number, literally 10-20 pages per minute.
> 3) Number of pages with type T_PAGE_LIST_NODE grows, number of all other
> pages remains constant.
> 4) Though, total number of data pages in free list remains constant (with
> minor fluctuations).
> We have to find out whether this process has a saturation point, after which
> pages number stops growing. Otherwise, it's a memory leak and should be fixed.
