HI Nathalie,
I'll need more information.
1. What actions do you take to cause the run?
2. Does the error occur when you start up Kepler or when something else
happens?
3. Are you running from the Kepler development source distribution or
from Kepler-2.2?
When I run the Kepler development source distribution, I get:
[run] JVM Memory = 5m 768m
Your run has:
JVM Memory = 512m 512m
For my set up, kepler/build-area/settings/memory.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd";>
<properties>
<comment>Modified Memory Properties</comment>
<entry key="max">768m</entry>
<entry key="min">5m</entry>
</properties>
Does your memory.xml file set the min to 512m?
It turns out that the min value is not actually the minimum value
./build-area/src/org/kepler/build/project/MemoryProperties.java reads
memory.xml
./build-area/src/org/kepler/build/Run.java uses the value:
jvmMinMemory = MemoryProperties.getMinMemory();
...
java.createJvmarg().setLine("-Xms" + jvmMinMemory);
I set the min key to 512m and Kepler started up for me and I was able to
run a model.
I'm not familiar with Scientific Linux, but Wikipedia says it is based
on RedHat Enterprise Linux,
which is what I'm running. Perhaps your machine does not have very much
memory?
Under RedHat, the "free" command returns the amount of memory available:
bash-3.2$ free
total used free shared buffers cached
Mem: 16015360 13872904 2142456 0 1239668 8394912
-/+ buffers/cache: 4238324 11777036
Swap: 2031608 280 2031328
Also, from the command line, try:
java -Xms512m -Xmx512m -version
I get:
bash-3.2$ java -Xms512m -Xmx512m -version
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)
Note that requesting a very large amount of memory will fail:
bash-3.2$ java -Xms512000m -Xmx512000m -version
Error occurred during initialization of VM
