RAM Issues with zimbra on virtual host

[clemente]

I try to install Zimbra 6 on a Virtual Host running Ubuntu 10.04 64Bit. The host runs with up to 4GB RAM and has a guarantee for at least 1 GB RAM.

The initial installation runs well. When it comes to startup the system, I run into problems. What I read out of the log files is that zimbra cannot startup a Java VM because Java cannot allocate the initial amount of RAM.

Fiollowing log entries show "cannot fork due to lacking memory" and so on.

I monitored systems total RAM usage and found that the zimbra startup consumes nearly 4 GB RAM when the trouble starts. The major RAM consumers are several Java processes.

I am no virtualization-pro, but I think that the startup process tries to allocate more RAM than the host can get from the real hardware. those 4 GB are not guaranteed.

Does anyone knows about such problems and can I somehow install zimbra on this virtual machine?

Thanks a lot!

What sort of 'virtual host' would this be?

Then you need a host that can guarantee (at least) the required RAM for a Zimbra server.

Did you search the forums and/or for further information on this problem?

Thanks for your suggestion.

I try to give all information and start with your last question: Yes I sarcheed this forum and other virtualization related forums.
As stated I am no Virtu-Pro, so maybe I do not know the correct words to search for. I tried failcnt, beabcounter and so on. As far as I understand the story, there is not that much to tune at server side.

Zimbra people write about 1GB RAM to start with wwhat xactly matches my virtual machine. What do you exactly suggest as guaranteed RAM?

Can you or someone else please give a hint what I can do?

Last open question: It is an 1&1 VServer XL. If this really matters.

Thanks a lot!

I presume that the server you're using is OpenVX, unfortunately that isn't a supported platform for Zimbra and you may or may not get it working. The problem is likely to be the RAM that's allocated to your server. I don't know anything about OpenVZ so you might want to take a look at some forum threads on the topic: site:zimbra.com +openvz - Yahoo! Search Results
