Zimbra installation fails (Debian)

[info]

Hi!

I wanted to try to install zimbra on my debian based webserver today, but installation always fails with the following output.

output console:
===========

zimbra-core......zimbra-core_4.0.3_GA_406.DEBIAN3.1_i386.deb...FAILED
###ERROR###

zimbra-core_4.0.3_GA_406.DEBIAN3.1_i386.deb installation failed

Installation cancelled

How much java object space does Zimbra need?
Is there anybody out there, who can help me with my problem? :-)

How much memory do you have?

[info]

about 512 mb.

too little, i think 2gb is recommended and I struggle to run it on debian with 1gb. do you have other stuff running on the machine that you can shut down? what does free return?

thanks for your answers.

it there no way to make it run with 512 mb ram? :-(
maybe a lightversion of it?

hi,

it is possible to install and run zimbra with very few ram.
using this installation is my task in the next few weeks.
for tuning some (rather basic) tips are in the wiki (wiki.zimbra.com), but for very simple and single use, I am going to reduce apache childs.

for debian 3.1r4 i can offer the dependant packages names.

of course this kind of installation is not recommended as productive ect pp,
but to get in though with it (vmware on homepc) is does quite well.
