I am trying to install zimbra server on a low spec virtual machine running ubuntu 10.04. I do meet the requirements as documented here (1 GB RAM/5 GB free disk space).
I got the virtual machine specifically for this purpose, so can install anything that helps to run zimbra.
The error I am getting is this:
zimbra@cloud:~$ bin/zmcontrol start
Could not create the Java virtual machine.
I am pretty sure it is something to do with not having enough memory for the java virtual machine - but I don't know how to reduce the requirement, or how to free up memory on the system.
Has anyone got zimbra to work on 1GB RAM? How can I do this?
Edit: more details...
