Trouble with creating virtual hosts

Help! (Home for newbies)

Hello there again,

The last question for the night. I am using a VPS with Sentos 5.5 on the VPS. I was creating a Virtual server and I am getting through most this but there are a couple places where it fouls up. The first place being the mail and in that case I went in to root and did a:

postmap “/etc/postfix/virtual”

with absolutely no errors from the command line and then it had trouble doing the webalizer setup for the server. This is where it stopped. i am pasting below the actual output of the error:

That as far as it went. Thanks anyone for helping me out.

Hmm… this in combination with your other post are starting to make me wonder if Virtualmin is running into resource limitations while trying to execute processes.

Is there a file on your system named “/proc/user_beancounters”? If so, what are it’s contents?

here is the output from user_beancounters:

Okay, from what I see in the output there – you may not have enough dedicated RAM.

It looks like only about 340MB of your RAM is dedicated. It looks like you have 540MB of burst – but that’s not guaranteed memory, anything in that realm can be killed at any time to make room for RAM in other VPS users on your server.

I think what you may require is more dedicated RAM – and even at that point, that’s considered a low-memory system, you’d want to make sure your using as little RAM as possible. You can use this document to get some ideas on limiting memory usage:
