Subject Re: Out of heap space with simple updates
Date Wed, 23 Jan 2008 19:57:36 GMT
I'm using

    java -Xms512M -Xmx1500M -jar start.jar

which gives the Java VM a min heap of 512MB RAM and a max of 1500MB. I
don't know if 1500MB is enough to fix your problem. I do know that
when I try to increase it much beyond there using the standard Sun VM
on Windows 2003 Server, Java refuses to start.
