No, I don't think so. Because I'm not using supercolumn and size of a column will not exceed

Ämne: What is consuming the heap?
In my cluster, I have set both KeysCached and RowsCached of my column family on all nodes
to "0", 
but it still happened that a few nodes crashed because of OutOfMemory
(from the gc.log, a full gc wasn't able to free up any memory space), 
what else can be consuming the heap?
heap size is 10G and the load of data per node was around 300G, 16-core CPU, 1T HDD
