Thanks Paul for information, it very informative. But how this work at others. I see that situation stay better when i increase heap size to 7GB, but nodes still frozen truth not so frequent as before, but still, also but I don;t probe this i think that setting -Xmn to something bigger then 800M may give benefit ( http://java.sun.com/performance/reference/whitepapers/tuning.html)
