RE: Java memory leak? -- WDSCI-L

Thanks, Mike

The most I can get through DELL is 512 meg - a Dell 4800. We'll see.

If I read the article correctly, the default maximum for Java heap (max memory?) is half of physical memory - that'd be 128 meg and seems to fit the behavior - it seems to go up to around 120 or more, then back down to something, 64? So if I leave things alone, does this work?

BTW, all the work I do is editing CL, CMD, and C source from the 400. No Java, no Webfacing, none of those intensive things. I could do everything in CODE and be very happy.

It still disturbs me that it grows while it is minimized, while I am not doing anything. Must be collecting garbage?

If you can, you would get better performance with WDSC (4 or 5) if you went
to 1G of memory.   256M is simply not enough, 512 is slow, 1 G is OK.  In
my experience anyway.  If you need to run it on a machine with only 256M
then you probably want to close all other applications to free up as much
real memory as possible.

It's probably fine that the Windows swapper be large but you don't want to
set the max memory of the JVM for WDSC to be larger than real memory.

Kind regards,

Mike
