---------------------------------------
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.
