Just reopening this issue. Unfortunately I could not analyze the heap dump which is of 25GB, so I could not do any analysis with this.
What else can go wrong, however I could see 500 to 800 active thin client connections on each node, can this cause this I see our heap memory utilization is more than the off-heap memory and its hosted on VMs, anything I can verify on the underlying hardware ?
