Prem - Thank for your reply. You explained why Ignite container grew from 2.5G to more than 4G because there is 2G heap memory and more than 2G off-heap memory, I think what you said is very correct and solve one of my main problems.
But another question, why system memory cache also grows slow and never be reclaimed. As I know Linux kernel will reclaim system memory cache automatically when lack of memory. The memory cache I mentioned before refer to the 'buff/cache' that printed by 'free' command -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
