             Summary: Client heap starts constantly growing when server offheap memory gets full
                 Key: IGNITE-6302
                 URL: https://issues.apache.org/jira/browse/IGNITE-6302
             Project: Ignite
          Issue Type: Bug
          Components: general, streaming
    Affects Versions: 2.1
            Reporter: Ksenia Rybakova


Load benchmark is streaming data to grid. Page memory maxSize is set. Sometimes IgniteOutOfMemoryException is not thrown at servers when maxSize is reached. This is the first problem. The second one - client's heap starts to grow constantly after server's offheap memory gets full.

Load config:
- org.apache.ignite.yardstick.cache.load.IgniteCacheRandomOperationBenchmark is used to stream data
- 1 client, 4 server nodes
- client heap:  -Xms20g -Xmx20g, server heap: -Xms4g -Xmx4g
- memory policy maxSize: 5Gb
- page size: 2Kb
- number of entries to preload: 35M

At some point servers reach max offheap size (number of pages in log doesn't change and this number matches 5Gb maxSize). IgniteOutOfMemoryException is not thrown and client starts to utilize more and more heap capacity.

All configs are attached.
