-----------------------------------------

             Summary: 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
             Fix For: 2.4


The following code creates local caches:

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(); 
    } 

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.
