Sorry hope this is the right place to post my question. When will I be able to get some work? Do I need to be patient, please let me know because all I get is that the server is temporarily down. I'm not a techie so please forgive me but I know you have had problems quess I just want to get this computer to do something worth while. Thanks

Is this a part of some of the recovery problems or what? It seems as if BOINC is able to access the servers, but none is responding or receiving?

Message 567600 - Posted: 15 May 2007, 3:04:19 UTC

I'm wondering if we should celebrate the arrival of new hardware and all the work being done in server swapomania by NOT 'unsuspending' our project use of SETI. It seems quite clear that the new (and still changing) configuration needs some air to recover. Downloads are currently a bit hit and miss, and uploads, well, uploads just ain't happening right now.

So perhaps by Wednesday (if there is no additional outage for backup tomorrow) or Friday would be a time to look at the project as being truly online ready.

That's what I suspected, but no improvement in at least 12 hours...? Shurely there must be some more glitches than a deceased drive and strained connctions, as it in the same post was said that "bruno has been taking up most of the slack". It doesn't seem as if Bruno is doing much of that to me.

ok: try this:
you hit the tab in boinc that says "advanced" and then "retry communications".

Look at the tab where is says "messages" and you will see what your computer is trying to do.

If this does not work the go to "proyects" tab and hit "update" and go back to "messages" to see what your machine is doing.

In any case you will not get a working until you get some wu into your machine and the results will not reflect on the different stats until you "send" all your results.

Hope this helps and do not worry too much... me, I just got some work for the Beagle and no results from Santa Maria, Pinta is "dead in the water" since some weeks ago, anyway.

Be patient and cool!

Ok, but you must remember, they have been down so long, that everyone has completed their work units, so now they have 1,444,386 computers trying to contact their server at once, so the connection is going to be very very poor until things start to idle down.....
Also some people still have their cache set for 5-10 days worth of work, so the server is actually going to need to make 10-30 million WU's untill it is actually caught up.....thats a staggering number "work load" for any server....especially considering the bandwidth needed to pump those WU's out.....this is also compounded by the fact that the few WU's being completed now are needing to be sent back to SETI......
So the wait could be longer than a 12 hour period, realistically, about a few days if not more....

In my case, I have three computer running. I who is farr so I just known that 14 WU where assigned, but the two others got some of them. The faster one set to 5 days between communication has downloaded 13 WU here of 5 are finnished, and the other one set on three days has donloaded 9 wu where 6 are completed.

A question is what will happen to the wu's uploaded just before the problem or the one's who where reported has timeout during the outage period? for example this wu: http://setiathome.berkeley.edu/workunit.php?wuid=126729761 is reported as "No reply"
Just to know.

Thanks for the job and the update,
Good work Matt (And the others who have helped solving the issue ;-) ).

So far It been almost 12 hours and I think I've restarted the PC once for M$ and I've uploaded a WU and reported a grand total of 1 time each, Something is Broken.

I'm beginning to agree.

1) The network bits/second should not be declining while my ability to download is still effectively nothing.

2) The network bits/second should not be declining while my ability to upload is nothing.

If you look at the graphs you should notice something "out of spec" right away, in that outbound bytes are spiking WAY out of average, and sometimes higher than receiving. I think, as mentioned in the first post, the problem is simply flooding the network connection on their side. The BOINC client has never been very happy about unstable connections, and I think that's what we're dealing with at the moment.

I'd say it should sort itself out over time, except that with over 600,000 users and a week of backlogged workunits, we (users) may be generating enough traffic to keep it in a constant state of flux until/unless Berkley does something on their side to throttle it down to something the servers are happy with.

Edit: Hey Batman, don't suppose you could be convinced to move those logs someplace else so that it's a link rather than something we have to scroll past? Just a thought.

Just a bit of the log would have been sufficient.
Posting all that tends to just annoy & irritate others, and people that are annoyed & irritated tend to be not so helpfull to those causing the annoyance & irritation.


Something is Broken.

As Matt mentioned in his opening post Bruno is stressing under the load & dropping connections here there & everywhere, which of course exacerbates the whole situation. This is in addition to it's tendancy to do odd things at random & a reboot during tomorrows outage should help settle it down, which should help reduce the load on it much faster. Which should help to keep it happy.

What looks really wierd to me is it's jagged appearance. Normally the load maxes out for a while & then drops away- but that graph shows lots of short frequent periods of no data throughput, and even as the load is slowly dropping those anomalies are still occuring.

...
The server situation will be in major flux, and generally in a positive direction, over the next week or so. I'll be trying to keep updating the server status page, but I make no guarantees about its accuracy.

Thanks again for your patience during the past couple of weeks. While I appreciate the kind words and sentiments I should point out that this past weekend for me wasn't exactly restful time off. I was working at
my other job.

- Matt


Yeah, Matt. This was a crazy weekend! Thx for all the info. We'll try to be patient while reconfiguring thumper and the other servers ;)

About the spikes on the graph:

    *Matt mentions that yesterday was cutting some wires on the rack: The deadline was 'cause the servers was unplugged from the net
    *Bruno chocked: No data was transferred to Boinc clients
    *Bruno is on again, but overloaded: Boinc clients will take the work slowly
    *'Cause this overload, bruno can appear as disabled on the status page



So, we must be patient ;) Everything is on, but there're many work on queue.

I think the http errors are getting less

Think of it this way you are trying to copy a 100 files in 100 copy instances it takes ages but as soon as some of them finish copy speed increased alot

there must stil be alot of unsend units out there but they can only get les
bruno si still under stress it shows "disabled"
