Actually, it seems to do both according to my profiling software (Using Inprise Optimizeit). I can see when the garbage collector runs, and when it does all the objects are reclaimed and it deallocates, but my resident memory keeps rising.

I noticed that each of my java processes (individual java threads) comes near that before the "out of memory" error. Perhaps that is what I am noticing. I still do not know why I am getting it though. > > Could it be that you simply need more than the default 64MB memory? I don't know. The machine has 1GB of physical and 2GB virtual memory. With the total of java processes at 64MB each and 57 of them running, my machine is almost depleated. > > Yoav Shapira > Millennium ChemInformatics > > > >-----Original Message----- > >From: Leo Przybylski [mailto:[EMAIL PROTECTED]] > >Sent: Wednesday, December 11, 2002 7:18 PM > >To: [EMAIL PROTECTED] > >Subject: Memory issues > > > >Hello, > > > >I'm having memory issues.
