> 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: Andrey Aleksandrov
> Priority: Major
> Fix For: 2.6
>
> Attachments: Demo.java
>
>
> 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.
