Dmitriy Pavlov updated IGNITE-4959: ----------------------------------- Fix Version/s: (was: 2.6) 2.7 > 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 > Priority: Major > Fix For: 2.7 > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
