And with the Workunits-waiting-for-validation backlog finally clearing (a peak of almost 11 milion, now down to 8.3 million), and the Workunits-waiting-for-assimilation starting to catch up as well (from 2.5 million down to 1 million (things working normally value being 0)), that's leading to a backlog in Workunit-files-waiting-for-deletion (from 0 to over 1 million & climbing (things working normally being 0)).
And they can't be purged, until they are deleted.

And since the db purge & some of the file deleters run on Bruno, which is the upload server, it would be nice if we could get the new hardware running here on main to help things along.
Something for the new year's wish list.

But it seems as if the new SSD upload server that was tested on Beta failed (file system error) last Friday, according to Eric's post.
It didn't last long even on the low production Beta project. So any hope of that one coming to Main in the near future isn't high.

Fingers crossed it was just a software issue, not hardware.


Speaking of issues, we're back to getting nothing but "Project has no tasks available" messages, again.

No such problems here, but then I do not ask for many tasks, and not very often either.

It just started happening an hour or two ago. You probably would see it next time it tries to fetch work. :-(

And now picking up work again. Posting about a problem often sorts it out.
Till the next time.

After all the discussion before the previous outage I have my parameters set for "1 day of work" but only check in once every 6 hours or so (0.25). I used to be setup so it would contact every 5 minutes or so to keep my cache topped off.
Since that last disaster I said "Well, be that way" and set it to the 0.25 (per day) setting.

It seems like my Cache is staying filled sufficiently and my logs are a bit shorter :)

pre panic.

The RTS is 90K and falling. The return rate is around 150k which is a bit high, and the system seems to be more interested in assimilation that splitting. We should have full caches, but I thought I'd post why we will get 0 WUs available messages. Think all we can do is wait it out.

I've sent myself to NNT as I have a slow machine and can wait until the RTS is flush again.

(you happy now Tom :P)

Hi All

I haven't been very active the last couple of years or so, I thought I might fire up a box or two now that SAH has had the time to fix the software/server/WU availability issues that had been plaguing them...


The response was a thunderous silence - did I somehow offend someone?

Possible everyone was incapacitated laughing about the assertion that the "software/server/WU availability issues" have been fixed?
lol
It's been a pretty rough patch here with server issues lately . . . but welcome back !!

No. You just posted at a unfortunate time. There was issues with the server code right then and it took several days for the issue to be resolved. The server is back up and running with occasional hiccups. What kind of information do you need?

Not everyone uses the "quote" or "reply to" buttons, but you were replied to. ;-)

It's taken a couple of weeks, but the Validation, Assimilation, Deletion backlogs have cleared. Now we just need the Purgers to catch up, and then maybe the splitters will be able to really get going and finally refill the Ready-to-send buffer.
Apart from a couple of periods where the servers stopped sending out work again, over the last day and a half work demand has exceed supply and the Ready-to-send buffer has been slowly but steadily emptying until the last few hours when the above backlogs were finally cleared out.

I had some communication issues with a host and lots of software questions but I am sure I can work the remainder out alone as well.

Your post also didn’t contain any kind of question. Just a statement that didn’t seem complete as you ended on an ellipses (...). Not sure what people were supposed to say.

But welcome back. If you have an actual question feel free to post it in the appropriate forum.

If you have issues then it's best to start your own thread and that way you'll get notified for all replies. ;-)

No, but if you had posted in one of the threads for general discussion such as "Don't know where it should go? Stick it here", or such similar thread in the CAFE Seti forum it probably would have been noticed & got a response there, as this one is for Server & other issues worth panicking over, and people were (as others have pointed out) in the middle of a panic at the time.

Or do a quick check to see if there is already a thread that concerns the issues you are having, and make use of that one if the answer to your question hasn't yet been provided.
