When starts several nodes (I have tested in 4 nodes) with the application, through some time (depends of heap size), we have got a Full GC pause and segmentation the grid.
After heap dump analysis, I found some suspicious object:
{noforamt}
  Class Instance Count Total Size 
class java.util.concurrent.ConcurrentSkipListMap$Node  63622411  1526937864  
class java.util.concurrent.ConcurrentSkipListMap$Index  31810595  763454280  
class java.lang.Long  63622318  508978544  
{noforamt}
