Re: Memory issue on kubernetes

[Pavel Tupitsyn]

maxSizeBytes is "256M or 20% of physical memory", try setting it explicitly.

Overall I think 2G is just too low for Ignite to work efficiently. You
have 400M offheap, 1G heap, some JVM and OS overhead, it is too tight.
I would start with at least 8G. Production use cases are usually 32G+ per node.
