Steve Loughran commented on HADOOP-4052:

And what happens when you set a ulimit of that size: JRockit refuses to play

> bash
slo@morzine:~/Java/Apache/hadoop-core$ ulimit -v 786432
slo@morzine:~/Java/Apache/hadoop-core$ java -version
[ERROR] Not enough virtual memory to start JRockit. 
[INFO ] If you use 'ulimit -v <amount>', make sure you specify the amount to at least
Could not create the Java virtual machine.
