I got this error when i added one extra line in /etc/postfix/master.cf Restoring master.cf to original fixed it.

Add a swap file and it will work. it seems this error occurs in many different scenarios due to memory issues. adding a swap file solves it in most cases or like @andy.pixiesky said add more memory.

I’ve just had a battle with this. I discovered this and a whole host of other problems is caused by a lack of RAM. You need at least 1GB to get Virtualmin to play nicely.
