rpminstall error with RHEL4 3.1 build

[eger]

I'm trying to setup on a virtual private server just for testing. I'll post the specs first since... it may not even be psosible with my specs.

128M (burstable to 384M) RAM
shared dual core 2.8ghz
5gig available space

Here is the error I get from install.sh:

Removing /opt/zimbra
Installing packages

    zimbra-core......zimbra-core-3.1.0_GA_279.RHEL4-20060331125835.i386.rpm...FAILED
###ERROR###

zimbra-core-3.1.0_GA_279.RHEL4-20060331125835.i386.rpm installation failed

Installation cancelled

And when I try that rpm manually:

[root@mx packages]# rpm -Uvh zimbra-core-3.1.0_GA_279.RHEL4-20060331125835.i386.rpm

I'm guessing this might be because of RAM. What is the absolute minmal RAM needed for an install?

If I can't do it with 384M might I get away with 512M?

If the install is possible with 384M RAM then where should i start looking? I have checked /opt/zimbra/bin and there are lots of zm files there but no zimbra binary.

Yes try 512. That is the minimum we recommend.
