Issues running grails on a remote environment

I have a server that is "named" and it seems to cause Grails to be unable to find localhost.

Running Grails application..
2011-01-12 20:45:14,046 [main] ERROR ehcache.Cache  - Unable to set localhost. This prevents creation of a GUID. Cause was: zaftra: zaftra

Contents of /etc/hosts (as shown):

127.0.0.1       localhost localhost.localdomain zaftra
::1       localhost localhost.localdomain zaftra

I'm going to assume that you're on some flavor of linux. If that's the case, you might have a look at your /etc/hosts file - is there an entry for localhost? I'd expect to see something like:

127.0.0.1     localhost zaftra
::1           localhost

I did some Googling - there's a similar question over on SuperUser - the suggestion there was to add the following to /etc/resolv.conf:

search (domainname) // in your case, search (zaftra)

You might also try:

search zaftra
// or
search zaftra.example.com // if there's a more fully-qualified domain name you can use

(That's based off of an entry I've got in resolv.conf on one of my Ubuntu machines).

I'm using AWS(running amazon linux) and ran into the exact same issue, my fix was to add this to /etc/hosts:

102.130.27.257     LAMP-LIVE01-N123     www.mydomain.com

where those values came from:

{internal IP}     {instance name}     {domain for grails app}

and then I restarted httpd and my grails app server(tomcat)
