public MemoryTest()

Method Detail

testOneEnvironment

public static void testOneEnvironment()
                               throws java.lang.Exception

The idea is to keep a ring of about 10 nodes alive, but one by one recycle the nodes out. In the end, creating a whole lot of nodes, to see if they are being properly cleaned up. TODO: make this return a boolean: Record the memory at start (M1), then after creating the ringSize*2 nodes (M2) (M2-M1/ringSize) is the approx memory for 1 node. M3 = (M2-M1) which is basically the amount of memory that our ring of 10 should take up. at the end of the test, record M4. if M4 > (M1+2*M3) then we probably have a leak, fail. TODO: test this with other environment settings
