examples in my Java Application,the Memory will not increase,the codes is below:
    for (i=0; i1000; i++) {
mapObj map = new mapObj(mymapfile.map);

 imageObj img = map.draw();

   but When I use the code in my servlet project,the memory will increase very 
fast the code is below:
  mapObj map = new mapObj(mymapfile.map);

   imageObj img = map.draw();
   img.img.getBytes();
  img.delete();
  map.delete();
 
can anyone tell me how to solve the problem?thank you very much!

I use System.gc() before  map.Draw() And the memory remains stable,
Currently I use Java 7, but earlier in java 6 also works
System.gc has several improvements in Java 7, you should try it

Thanks for your answer. Do you also use mapscript.jar in servlet?

Re: [mapserver-users] mapscript.jar in java

2012-09-11 Thread Umberto Nicoletti 
Please note that growing memory usage is not necessarily symptom of a
problem. On the other hand memory not being released IS a problem.

Invoking programmatically the garbage collector does nothing towards
addressing memory leaks and, almost certainly in both cases, will
reduce the overall JVM performance.

As far as memory leaks are concerned Mapserver/Mapscript should be
mostly leak free, but ymmv depending on the features you are using.
If you are afraid (or know) that mapscript is leaking memory please
run it through Valgrind, then open an issue with both a test case and
a Valgrind output.

Best regards,
Umberto
