[Building Sakai] sakai configuration / swap space

[Jon Wheat]

This continues to be a thorn in my side.  I'm not sure what I've done to cause this, but my box keeps crashing with an "Out of Swap space?" message.  I have to reboot it to get it started again.  Its gone down 5 times this weekend.  I rebooted it again this morning at 5:45 (planned) to possibly get it through the day, but alas it crashed a little bit ago.

It is a VMWare box, with 4GB RAM and 72GB HD. There is a 4GB swap partition.

I have this in /tomcat/bin/setenv.sh

JAVA_OPTS="-server -XX:+UseParallelGC -Xms1024m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=256m -Djava.awt.headless=true -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"

export JAVA_OPTS

I just now added the -Xms1024m (which was missing before) and upon suggestion from a JAVA guy, changed the MaxPermSize from 512 to 256 to match the PermSize, so we'll see if those changes help.

I think over the weekend, I've tried a bunch of different things with this file, so I've tried many different settings.  I actually do not think the VMWare box is configured for multiple processors, so I think maybe that UseParallelGC should go?

any advice would be greatly appreciated, I feel like this is a dark art - and I'm far from being a warlock.
