New error since upgrading to 7.1.2 Build 10978 on Ubuntu 11.10. Whenever I attempt to reindex my email from Setup--> Reindex I get an error message:

Invoice Connection refused, server: localhost

Is this simply a permission issue? Or am I missing a service that should be running in /etc/services? My /etc/hosts file looks like this: lucidlynx localhost.localdomain lucidlynx
::1 lucidlynx localhost6.localdomain6 localhost6

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

"lucidlynx" is the hostname of my computer.

I can not run Reindex as a result of this error.
