----------------------------------
Summary: 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
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 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 stop growing. Otherwise, it's a memory leak and should be fixed.
