Hello all,
It's been a long time coming - it's a full ticket review. Yey!? This is actually probably the only look at all the tickets we'll get this month,
so lets savour it.

38 Open Tickets this month.

RALPP
https://ggus.eu/?mode=ticket_info&ticket_id=139539 (5/2)
A ticket from Duncan regarding blocked perfsonar ports. The host is failing to talk to itself due to odd reasons. Any luck finding the time to look again at this? Duncan posted a few hints a month ago. In Progress (14/2)

OXFORD
https://ggus.eu/?mode=ticket_info&ticket_id=140134 (11/3)
Atlas jobs seeing an "Unspecified grid manager error". The classic grid error. Prompted the discussion about atlas asking for jobs not to be killed due to using too much memory. Oxford have raised their default memory per job to 4GB (and they won't kill a job unless it uses 1.5 times that). Waiting to see if that fixes things. How does it look atlas side? Waiting for reply (2/4)

https://ggus.eu/?mode=ticket_info&ticket_id=138647 (3/12/2018)
T2K DFC migration ticket. If I had left it a few hours this ticket would be closed, Kashif has successfully renamed the files without having to do anything DOMEy. Daniela is re-registering the files in the DFC and hopefully this will be sorted soon. In progress (8/4)

https://ggus.eu/?mode=ticket_info&ticket_id=131615 (3/11/2017)
Oxford's IPv6 ticket. Kashif provided a light update last month, still not much movement but there are plans made. On hold (13/3)

BIRMINGHAM
https://ggus.eu/?mode=ticket_info&ticket_id=140573 (4/4)
A request from biomed to update the .lsc information. Is this even relevant for your site anymore? Either way the ticket needs acknowledging (or straight up "not relevant to our site"-ing). Assigned (4/4)

https://ggus.eu/?mode=ticket_info&ticket_id=140584 (4/4)
A ROD ticket for your cream CE Birmingham only has to not get these tickets. Looks like a simple lcg-CA (or whatever they're called these days) updated needed on your WN. As this ticket also hasn't been noticed I wonder if Mark was off work on the 4th? Assigned (4/4)

https://ggus.eu/?mode=ticket_info&ticket_id=131612 (3/11/2017)
Birmingham's v6 ticket. Things were progressing nicely but slowly back in February. Any time to have any joy on this since then? In progress (5/2)

GLASGOW
https://ggus.eu/?mode=ticket_info&ticket_id=140151 (12/3)
LHCB jobs seeing "can't start new thread" errors. The problem isn't understood as far as I can see but it appeared to disappear on its own - on hold to see if it comes back. On hold (27/3)

https://ggus.eu/?mode=ticket_info&ticket_id=140222 (15/3)
MICE DFC migration ticket. Daniela repoked to ask for an ETA on getting those checksums. In progress (15/3)

https://ggus.eu/?mode=ticket_info&ticket_id=131611 (3/11/2017)
Glasgow's v6 Ticket. Any news in the last two months about why your v6 performance is pants? In progress (5/2)

DURHAM
https://ggus.eu/?mode=ticket_info&ticket_id=131609 (3/11/2017)
Just a v6 ticket at Durham. Really could do with an update. On Hold (4/12/2018)

SHEFFIELD
https://ggus.eu/?mode=ticket_info&ticket_id=138649 (3/12/2018)
T2K DFC migration ticket. Elena is asking Kashif for his secrets in renaming DPM files. On Hold (8/4)

https://ggus.eu/?mode=ticket_info&ticket_id=131608 (3/11/2017)
Sheffield's v6 ticket. Really, really, really needs an update. And probably putting on hold if there are no postive updates. In progress (30/10/2018)

MANCHESTER
https://ggus.eu/?mode=ticket_info&ticket_id=131607 (3/11/2017)
Just the v6 ticket here. Please please can we get an update here? And again, if there is not positive news expected can it be set on hold too? In progress (3/12/2018)

LIVERPOOL
https://ggus.eu/?mode=ticket_info&ticket_id=139411 (30/1)
What's the plan for this biomed space token ticket? On hold (1/2)

https://ggus.eu/?mode=ticket_info&ticket_id=138648 (3/12/2018)

https://ggus.eu/?mode=ticket_info&ticket_id=131606 (3/11/2017)
Liverpool's v6 ticket. As we're at the start of a new FY are plans being formed for the new network upgrades? On hold (6/2)

https://ggus.eu/?mode=ticket_info&ticket_id=139683 (14/2)
Not really a problem, the decommissioning ticket for the site's SL6 CE. Nice and by the book. In progress (12/3)

UCL
https://ggus.eu/?mode=ticket_info&ticket_id=139101 (8/1)
ROD APEL-Pub alarm for UCL's VAC cluster. I think the site is a bit dead in the water here - has there been any news or progress? At last check Ben couldn't install ViaB so was stuck. In progress (4/3)

RHUL
https://ggus.eu/?mode=ticket_info&ticket_id=131603 (3/11/2017)
RHUL's v6 ticket. No news on this since January, is there still no news? Are the right people being prodded and poked? In progress (23/1)

QMUL
https://ggus.eu/?mode=ticket_info&ticket_id=140190 (14/3)
LHCB seeing FTS problems. After a lot of poking it seemed the problem went away after a few service and node restarts for unrelated reasons. Brian notices that the FTS monitoring is looking okay now - can this ticket be closed? Or do we want to watch it a bit longer? In progress (2/4)

https://ggus.eu/?mode=ticket_info&ticket_id=140628 (8/4)
Atlas jobs failing because the work directory is too large (wait, what? Too much space?). Fresh in today - Dan is on the atlas cloud support list getting advice as I type. Assigned (8/4)

https://ggus.eu/?mode=ticket_info&ticket_id=138364 (19/11/2018)

https://ggus.eu/?mode=ticket_info&ticket_id=134573 (17/4/18)

BRUNEL
https://ggus.eu/?mode=ticket_info&ticket_id=140619 (8/4)
CMS transfers of a file failing, due to a classic disk server down error. Raul is working to bring it back from the brink. In progress (8/4)

https://ggus.eu/?mode=ticket_info&ticket_id=140223 (15/3)

Another CMS ticket due to the same server being down. In progress (5/4)

THE TIER 1
https://ggus.eu/?mode=ticket_info&ticket_id=140599 (5/4)
LHCB data access problems. Restarting a castor server seems to have got things going again, can this ticket be closed then? In progress (5/4)

https://ggus.eu/?mode=ticket_info&ticket_id=140577 (4/4)
Really a ticket to LHCB, George noticed loads of file requests coming in with no service class defined, which has the potential to cause issues. It is being looked at (Matt code for I scanned the ticket and got lost), as of Friday there still were a few files coming in with these symptoms. In progress (5/4)

https://ggus.eu/?mode=ticket_info&ticket_id=140447 (27/3)
The ever vigilant Duncan spotted v6 outbound packet loss on the RAL perfsonar. Investigations went underway - any results? In progress (2/4)

https://ggus.eu/?mode=ticket_info&ticket_id=140220 (15/3)
MICE DFC migration ticket. Daniela has batted questions at both the VO and the Tier 1 today, so it's still ongoing. In progress (8/4)

https://ggus.eu/?mode=ticket_info&ticket_id=138665 (4/12/18)
MICE LFC problem ticket. With the progress on the previous issue I think this can be closed (to either solved or unsolved)? On Hold (30/1)

https://ggus.eu/?mode=ticket_info&ticket_id=140589 (4/4)
A case of killed LHCB pilots at RAL. James confessed to an accidental docker restart across many nodes that could be responsible for the carnage. Some more investigation is being done, are jobs still being killed? In progress (4/4)

https://ggus.eu/?mode=ticket_info&ticket_id=139672 (13/2)
No LIGO pilots running at RAL. Efforts were made but sadly no fruit was born from them - and there's been no news for a month. Is this being looked at offline? The last update from the VO had a pleading tone to it. In progress (5/3)

https://ggus.eu/?mode=ticket_info&ticket_id=138033 (1/11/2018)
The old atlas singularity jobs failing ticket. This was closed for a while, but Alessandra has reopened the case - the last batch of tests revealed some issues with the RAL configuration. Reopened (6/4)

And that's it for the tickets. Catch you tomorrow!

Cheers,
Matt
