Re: [ptp-dev] EPP Kepler RC3... (Win32)
Xmx512m is far too small for kind of normal development, so this would cripple the other platforms. If you want to make it 1500m, I'm ok with that, but no lower.

I think the issue in the past has been out of memory exceptions with the smaller numbers

My(old)  WinXP sys with 3GB RAM would not work with

    -Xms512m
    -Xmx1536m
I bumped it down to
-Xms40m
-Xmx512m

as you suggested and it did at least come up.

Here's the discussion on the problems we had with SR2:

why is our default anyhow so large? that could also be an issue on non-windows machines with little memory, a VM, or a shared machine.
cpp and rcp (also for 64bit) use:
-Xms40m
-Xmx512m

I can't imagine that we need that much more. If so that seems something we might want to look into fixing.

Roland.

    Ha. I already had one.
    It's a good thing I write FAQs, because when i get the error again and forget I wrote one, I can read it myself.

    http://wiki.eclipse.org/Parallel_Tools_Platform_FAQ#Q:_What_do_I_do_when_i_get_.22Failed_to_Create_the_Java_Virtual_Machine.22_launching_on_win32.3F
    I added some info about the win32 total memory limitation.
    See if you agree with that, wordsmith it if you don't.

    Hi,

    I forgot to mention. I didn't test it on a win32 machine. I tested the 32-bit EPP (and also 64-bit EPP) on a 64bit windows with both 32bit and 64bit java installed.

      Thanks Roland.  I had trouble with it on an old machine and couldn't get ANY of the values to work, so chalked it up to the machine being very very old.
      We've had troubles with those values on various machines.
      Dave W, can you test it on the machine that didn't work for the other values for you?
      Can anyone else test it on a win32 machine?

      Good catch Roland.
      I also need to add an item to the FAQ to remind us that's what that error message means.
