Hi
I am tracking my virtual machines size on a solaris box using top and i am wondering what the memory outputs are SIZE and RES.
I think we have a memory leak and i have set the virtual machine heap size between 128 and 300. the SIZE shows as 179 constatntly but RES rises. If it was properly garbage collecting would the SIZE stay constant or RES?
Cheers much for any information or help at all.

In top the SIZE field description is the size of the task's code, plus data, plus stack space, in kilobytes. The RSS field description is the total amount of physical memory used by the task in kilobytes.
So if the RSS value is rising and not the SIZE value I would assume you have a memory leak.
I hope this helps
