Hi All, I have a 3 server cluster with RF=2. My heap is 2G out of a 4G RAM. The servers have 4 cores. I used default heap settings. The Eden space ended up around 60M and the Survivor spaces are around 7M. This feels a little bit low for a process that creates so much short-lived garbage. I just wanted to get your thoughts on this. Space used in the Old Generation stays in a short range 1.2G-1.6G but when the activity is low and I force GC it drops too 120M. It feels like there is a lot of garbage that does not have a chance to get collected. The server is running a batch load and its CPUs are 10-40% busy. The higher value is at 1.6G. Yet I am reluctant to push my data load because I do hit OOMs.
The amount of data loaded so far is small - around 100G in total. Should I increase my Gew Generation size? Thank you, Oleg
