All of my nodes show:  
ip heap.percent ram.percent cpu load\_1m load\_5m load\_15m node.role master name  
10.128.1.82 28 99 6 0.11 0.14 0.15 mdi - MYM 10.128.1.82  
10.128.1.25 37 99 6 0.59 0.28 0.21 mdi - HAD 10.128.1.25  
10.128.1.143 59 99 6 0.21 0.14 0.11 mdi \* PCH 10.128.1.143

I have no idea what is taking up the 99% of RAM. My configuration has no memory specific settings. How would I start to investigate the cause?
