When running the Live Blogging plugin (version 2.2.5), where the posts are being followed by a number of people, the server on which this site is hosted is being overload by requests for the following file:
Having looked at the logs from within the control panel, a high number of the 'hits' on that file are from my own ip address but the majority come from what appear to be the live readers of the blog.
Our host has had to block access to that file in order to stop the server overloading.
The site is http://www.tellywitter.com
The server only starts to receive high numbers of hits to that file when the live blog is started and running. When the site is not live blogging, there is no problem with over loading.
I'm really happy to provide any other information which would be useful to help solve this.
