Using a local proxy to reduce network traffic for CMS
Thanks to computezrmle, with additional work from Laurence and a couple of CMS experts (and my adding one line to the site-local-config file) there is now a way to set up a local caching proxy to greatly reduce your network traffic. Each job instance that runs within s CMS BOINC task must retrieve a lot of set-up data from our database. This data doesn't change very often, so if you keep a local copy the job can access that rather than going over the network every time.
Instructions on how to do this are available at https://lhcathomedev.cern.ch/lhcathome-dev/forum_thread.phpp?id=475&postid=6396 or https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5052&postid=39072

CMS -- Please set "no new tasks"
Hi to all CMS-ers. We need to drain the job queue so that a new version of the WMAgent can be installed.
Can you please set No New Tasks so that your current tasks can run out and no new jobs start? If you have any tasks waiting to run, please suspend or abort them.
Thanks, I'll let you know as soon as the change is done.

Problem writing CMS job results; please avoid CMS tasks until we find the reason
Since some time last night CMS jobs appear to have problems writing results to CERN storage (DataBridge). It's not affecting BOINC tasks as far as I can see, they keep running and credit is given. However, Dashboard does see the jobs as failing, hence the large red areas on the job plots.
Until we find out where the problem lies, it's best to set No New Tasks or otherwise avoid CMS jobs. I'll let you know when things are back to normal again.
