My war file which is about 12 mb, and has a lot of spatial data.
A simple applet lets the user peruse the map and draw objects and such. I noticed I was getting out of memory exceptions when I would continually reload it in the browser. I put in some code to capture the current amount of heap space used, and noticed that when I had all layers turned 'off' on my map the heap size would increase by 6-10 MBs each reload. When all of the layers defaulted to 'on' then the memory jumped by about 15-18 mb each reload.
Most of my layers are shape file layers, and are loaded in the openmap.properties file when the applet is started up. But even without layers the MapBean seems to be remaining in memory each load until memory climbed up to 500+ mbs and no longer loaded on the JVM. Is this all a known problem with applets, or is it a configuration I am doing wrong?
Thanks for any help to save the heap.
