How to minimize the use of memory ?

I have problems with a memory leak in my JSP file. I'm not sure, of course,it is in there, it could also be something in Internet explorer (5.5). If I let the explorer open for 12 hours IEXPLORER.EXE is using almost 150 MB of my memory.

I need to refresh my screen every 30 seconds and it is open all the time. Every 30 seconds I get a new vector with 20 records (objects) from the servlet. Do I need to set the vector to null after using them or are there some tricks/hints I can perform to reduce the use of memory ?
