Zbyszek B commented on IGNITE-7319: ----------------------------------- Gere is a code to reproduce: > Memory leak during creating/destroying local cache > -------------------------------------------------- > > Key: IGNITE-7319 > URL: https://issues.apache.org/jira/browse/IGNITE-7319 > Project: Ignite > Issue Type: Bug > Components: cache > Affects Versions: 2.3 > Reporter: Mikhail Cherkasov > Assignee: Alexey Goncharuk > Priority: Major > Fix For: 2.5 > > > The following code creates local caches: > {code} > private IgniteCache<String, BinaryObject> createLocalCache(String name) { > CacheConfiguration<String, BinaryObject> cCfg = new > CacheConfiguration<>(); > cCfg.setName(name); > cCfg.setGroupName("localCaches"); // without group leak is much > bigger! > cCfg.setStoreKeepBinary(true); > cCfg.setCacheMode(CacheMode.LOCAL); > cCfg.setOnheapCacheEnabled(false); > cCfg.setCopyOnRead(false); > cCfg.setBackups(0); > cCfg.setWriteBehindEnabled(false); > cCfg.setReadThrough(false); > cCfg.setReadFromBackup(false); > cCfg.setQueryEntities(<some basic query here>); > return ignite.createCache(cCfg).withKeepBinary(); > } > {code} > The caches are placed in the queue and are picked up by the worker thread > which just destroys them after removing from the queue. > This setup seems to generate a memory leak of about 1GB per day. > When looking at heap dump, I see all space is occupied by instances of > java.util.concurrent.ConcurrentSkipListMap$Node. > User list: > http://apache-ignite-users.70518.x6.nabble.com/Memory-leak-in-GridCachePartitionExchangeManager-tt18995.html -- This message was sent by Atlassian JIRA (v7.6.3#76005)
