VO Liaison CMSSpeaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))
I have been trying to fix the AAA service which has been causing SAM tests both directly for AAA and indirectly on the WN (xrootd-access) to fail over the last week or more. Also RALPP and other T2s in the UK were affected at times. I found the redirector based at RAL was full of logs. Chris and I cleaned up and restarted services. I also changed the throttling value on gw10 (not gw11) to try to allow more traffic, and hence give the tests a better chance of reaching our AAA. Restarts of all services from the proxies to the redirector (again) were then required. As of now, things are looking better, although we do see periods of passing tests, so it could just be that. I see no effect in the Vande monitoring of increased throughput from the changed throttling, so I don't know if that config is effective.
