Hi Uncle George, I also tried with the same thing of top and GC output. I had earlier noticed only on GC output, because top was not ported on my environment. However, after i observed both of them now, I have found that top output goes on increasing while GC remains the same (at around 300-700k). I have a native program in C which reads shared memory. When I commented the call to the native method and wrote some dummy thing there, the jvm doesn't increase now. I think there is some problem in my native code now. Thanks a lot since with ur hint i could isolate the problem. However, in native code also there is releasing of the arrays and other things. (The native code is written by some other person and i don't know much details about JNI either). Can you help me with some check points to find out the problem? Thanks a lot again, -sourabh
