Unfortunately I’ve had to remove the del.icio.us item from the sidebar. It appears that there’s some bad timeout values set in typo for retrieval of del.icio.us content – longer than the FastCGI process timeout.
This was resulting in the server becoming unstable, and causing machine load to spike which is no good, so until I can either fix it myself, or upgrade to the latest trunk of typo it’ll be switched off. You can still access it via the web or an RSS feed if you want though :)
