A network service error has occurred (zclient/io).

Hey World.
Well I am asked to have a look at a Zimbra server that is not allowing people to login to the web interface.

While trying to login to the web interface I get the following message with a nice big red icon above the login boxes.
A network service error has occurred (zclient/io).

Done a couple /etc/init.d/zimbra restart and cleared browser cache a few times. :-)

Log files produce nothing of interest.
View html source on the login page reviles the following java message:
