java on 2-4GB machine?
We have recently installed a cluster with Tiger MPX dual amd with 2-4GB.
These are running 2.4.19
I ran the following test code on a 4GB trying allocate
a lot of space to java (these errors were reproduced on
all machines).
import java.util.ArrayList;
class J {
public static void main (String[] args) {
ArrayList a = new ArrayList();
for (;;)
a.add (new Object [1000]);
}
}
$ java -Xmx3000m J
Error occurred during initialization of VM
Could not reserve enough space for object heap
Secondly I tried a smaller amount and it's a lot worse:
java -Xmx1000m J
1. The jvm crashes after running for a while(log below)
2. After the crash the jvm refuses to
java -Xmx1000m J &
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/VirtualMachineError
3. Libc is corrupted and the machine must be rebooted (hard reset
because init fails.
