Subject [jira] [Commented] (IGNITE-3516) H2 Indexing unregisterCache method does not cleanup resources and causes memory leak with OFFHEAP_TIERED cache mode cache.

Krome Plasma commented on IGNITE-3516:
--------------------------------------

Just to point out, this is hard to write test for. The best you can do is create cache, fill
it, drop it and repeat. The memory usage raises. I've been testing this patch for 2months
now on our machines and it seems effective.

> H2 Indexing unregisterCache method does not call TableDescriptor's GridH2Table close
and optionally GridLuceneIndex close, which causes OFFHEAP_TIERED cache to leak memory.
