    Subject: Denial of Service Attack?

Hi,

We are developing applets using Symantec Cafe2.0. Each Applet has lot
of widgets i.e. GUI components. Individually the applets work fine. But

when a user navigates among the applets, the Window 95 Resources(system,

user, gdi) go down slowly but surely; The Netscape communicator (version

4.4 with JDK1.1 patch) becomes very slow to the point of being
unusable.

I have tried putting
(1) System.gc() calls, System.finalization() calls in destroy method of
the applets
(2)I also have put the call
"netscape.applet.Control.setAppletPruningThreshold(0)" so every loaded
applet, destroys up the previous applet.
But the resource leaks do not get plugged.

If anyone knows a way to avoid this denial of service attack, please
let me know.

Thanks,
-Sunil.
