I know it is a week away, but will there still be the usual 'Maintenance' on the 26th, or will it be sooner/later to accommodate holidays etc over the Christmas period? TBar......I frequently get instances where I have to manually 'update' and there are also quite a few times, when, I can (as an example) report 3 tasks and get no tasks in return, without any mention of 'no tasks available'. I'm now at 184 tasks in progress, from the 200 of 2 days ago. For what it is worth, I still feel that a number of apparent issues need resolving and preparatory work done for Parkes upgrades, so best to do it sooner rather than later.
Don't take life too seriously, as you'll never come out of it alive!

Hey - it seems the file 13ja07ad has been stuck for a while. Has anyone else noticed this? Or am I crazy?

Why would it Ignore one Host and just miss a single beat on the other Host sitting next to it?

Just the general perversity of nature & technology.

Edit-
The present work mix is a great example of that.
Here we are, just before the weekly outage, and most of the work i'm getting is Arecibo. And most of that is all shorties.

It's working, but just maybe a little slower than usual as AP's as well as MB's are being split off that file at the same time.

Cheers.

Maybe so, but it has been there for at least a day (or more), I believe. Shouldn't take that long, should it?

The replica is finally starting to catch up.
However the AP & MB file deleters are having issues again.

I think that you jumped the gun there. ;-)

. . But he is still right, I am getting "no tasks available" and just simply "no tasks sent" again. This issue is independent of work being actually available ... and manifests mostly on the most productive machines. It seems the schedulers have a limitation that prevents them from keeping work supplied above some unspecified rate. At least in the long term. Richard speculated that it was the transfer limit from the RTS queue to the download buffer (what I call the hopper) but I would think that would mostly manifest as shortfalls in d/l's rather than none at all.

Keith is right, B@tch about the servers and they reward you with work... Was down to about 25 and then the flood gates opened.....

Yes, I am having issues getting work too with lots of no tasks are available or only getting one task every 10-20 minute after returning 5-10 tasks. Trying the Triple Update gets some success for a while, but ultimately falling caches.

One of my machines is currently being starved. It's currently down by about 100 tasks and seems to have been holding there for a while. All four machines are connected to the same Ethernet switch, only one is currently having trouble. Reminds me of a rolling blackout, one or two machines will stop receiving work and drop by 40 or 100 tasks and then recover by itself. Then a bit later it will happen to another machine. The fastest machine seems to be almost unaffected.

Got home to find my cache running down as well. The triple update got it flowing again (at least for now).

I still have full caches here and I get 1 for 1 at every request so far today.

Yes, as Stephen mentioned, I do use 6:10:60 and the only time I suffer is if there's a real problem. ;-)

Cheers.
