[kepler-users] Trouble with VM when starting Kepler

[Derik Barseghian]

I'm not sure what's causing this. What OS are you using? Are you within cygwin? Are you passing any memory arguments to java?
Kepler uses a max of 512m by default. When starting in a suite utilizing the provenance module, max is adjusted to 768m.
You can try adjusting max in build-area/settings/memory.xml. If Kepler hasn't already created this file for you, you can:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<comment>Default Memory Properties</comment>
<entry key="max">512m</entry>
<entry key="min">5m</entry>
</properties>

You could also try passing JVM memory options (e.g. -Xmx) by editing and then launching using kepler.sh, which is created with ant make-startup-scripts.

I haven't had to do any of this in Windows XP. Let us know what you find out.

In prior versions of Kepler we were able to set the max memory allotment before opening up Kepler itself, but now there is a tool on the user-interface to do this... which doesn't do much good if you can't get to the interface.
