After deploying the new XWiki version we've found that it has file descriptor leaks that means that it gradually consumes more and more space under /tmp. We've identified one of the probably causes - dtrace saves the day - and are aiming to deploy a patched version of XWiki early next week. We'll send out a heads-up before we do the deployment, but it will probably be at short notice, and there may be more than one outage.
We'll send out an all-clear when we are done. -- Alan Burlison --
