Almost nothing is working currently, most of us are on backup projects.

I'm seeing the same thing you guys are - Scheduler time-outs, them come back 5 minutes later and get through, and pick up the ghosts from the earlier contact.

First tries at downloads time out, second or third time they come down like greased lightning. Must depend on which download server I hit.

A couple days ago, I set the host with the new GT630 to NNT for Einstein because I wanted it to actually get some Seti done so I could see how long it was taking 2 at a time. So I check on it today and find it doing nothing because all the Seti downloads are stuck. Grrrrr.

Seeing that even babysitting it wasn't going to get me Seti work as fast as it could be finished, I turned Einstein loose again.

Now I want to know why Einsteins that are due on 1/12/13 and estimated to run in 5:32 are running HP ahead of the one Seti I managed to get that is due on 1/11/13 and estimated to run in 21:32.

Meanwhile, my i7 suddenly had a surge of successful downloads. It got everything and asked for more, and was resent 20 ghosts. Then another 20 ghosts. Then I discovered a typo in its hosts file and fixed it. Now it's moving downloads in little bits at a time (no networking pun intended). Maybe I should take out that line in hosts. [edit] Or change it from georgem to vader.

My upload timeouts began about Wednesday and got worse day by day. Noticed that my RAC rose and rose from Dec 5th until Dec 27th time point. I am getting work unit limit reached even on my little i3 notebook without dedicated graphics. Nothing is working here anymore. Am switching to alternate project GPU Grid and Rosetta @ Home today. Have tried proxy servers and no new work setting used during that very bad set of scheduler/server problems from November to early December time period. This last two + days feels as bad as the last meltdown.

Yes, I synchronised my home machine with NTP (I presume the Labs are too; my lab servers are) and observed that after my PC sent a request for more work both the time-stamp on my "Last contact" and the "Sent" time for (a) recent file(s) updated to 3-5 seconds after my request time. Sometimes the scheduler request would time out, other times I got notification in 5-20 seconds that there was more work, often in the form of ghosts if the file entry existed before my request. Seems the database is updating quickly, but somewhere along the chain the return of information about the new file(s) is disappearing.

It's still sometimes taking me around 5-10 minutes to complete a simple file upload. Once that is accomplished, the rest seems to work fine. If you are working on 20-40 minute long tasks, as myself, it's not that much of a problem. First step is to Fix the Upload Server.

All the problems started when 4th and 5th AP splitter went online. That was the only visible change after the maintenance outage.
Wheather this is server overload problem or network congestion.

They should stop those two and my bet is everything will return to normal as it was for a few days before.

The splitters are working better than they have for months, the assimilators are finally keeping up.
And it appears the Scheduler is no longer giving errors, it's just a shame it's not possible to upload and almost all Scheduler requests result in a timeout.


EDIT- and once again for some unfathonable reason, setting No New Tasks increases the chance of not getting a Scheduler time out. It still happens, just not as regularly as when trying to get work.

Panic mode? Again?

I know to the funding issue, I have made my donation, but....

Good luck for next year, I'm officially off-line again. Power bill vs S@H....

Set all my crunchers to NNT, only left Beta Big units to crunch to research.

Easy to test, isn't too complicated! I think it's worth testing it!

FWIW Uploads are uploading with an occasional Retry
to help it along , downloads are downloading,
the GPUs are staying busy with SETI. Rosetta and Einstein
on the CPUs. I'm only running 1.0/.01 for Cache.

Maybe a smaller Cache works better in the present circumstances.

As I recall, during the other 'Psychotic Server Episodes', the Uploads continued without any problems. It never took longer than a second or two to complete the upload. This is what has been going on since yesterday, around the time the Multibeam Shortie Storm began;

....

That's 7 minutes to upload one file. If that would have been last night during the height of the SS, I would have had another completed task before that one uploaded. In fact, I had around 8 stalled uploads at one point last night. If I got them all to remain active long enough, the report went through and I received downloaded files. If one was stalled, nothing worked. Things calmed down when the SS passed and the 4 minute MBs were replaced with 20+ minute MBs. Right now, I'm completing the Upload before the next task is finished.

The way I see it, the latest problem began when someone decided to release a Shortie Storm on a malfunctioning Upload Server. The Upload Server is still Borked.

Even before the shorties, uploads & the Scheduler were both stuffed.
At least ince the shorties haved stopped arriving things aren't as bad as they were- i wouldn't say they've improved as things are still seriously screwed. But they're not as bad as they were (uploads still take ages & i'm still getting them backing up & Scheduler requests still timeout although the number of errors has dropped).

I really haven't had any trouble with downloads. Other than the scheduler continually trying to give me all ATI MBs and nothing for the nVidia card. I just made the transition from all MBs to half APs & half MBs. Things are working well except for the Upload Server problem. Here's the latest one, 11 minutes and note how the scheduler didn't make a peep during that time. As soon as the upload completed, the scheduler kicked in and topped me off at 200 again.
