Speaking of parsing the log, check this out. This is the failed to validate result http://setiathome.berkeley.edu/result.php?resultid=594959001. I think this is clearly a core client error, not Seti application error. Only three seconds betwee computation finish and result upload. Note that I DO NOT use the '-return_results_immedeately' option.

As a reminder,
* Boinc is 64-bit Window version 5.10.13 from boinc.berkeley.edu
* Windows application is 2.4_Windows_x64_SSSE3.
* (from http://setiweb.ssl.berkeley.edu/beta/forum_thread.php?id=1002)
Connect time is set to 3.25 days.



Then I think this is a problem we discussed here in this thread:

Because of the 'validate errors'

After the update of the server-software you need little time between upload and report.. I use 0.002 days, this are ~ 3 minutes.
But if it's like you posted, then..


And.. thank you for looking!

Sorry, Michael, that does not reveal the problem. Your resultid=594959001 was reported at 12:55:35 UTC or about 99 seconds after its "finished upload" message. The one being reported with the scheduler request you show was uploaded earlier. It's the "finished upload" which triggers the transition from "Uploading" to "Ready to report", so the critical time gap is between that and the next scheduler request. You might want to check that gap, in case your clock and Berkeley's aren't exactly in sync it could be more or less than the apparent 99 seconds.

For all I know, 99 seconds may sometimes not be enough when the servers are under heavy load, but it seems to me if that much lag in the backend happened often it would cause other more obvious problems.

This server time is not synchronized to anything. It really should have been! At this point of time, the server time is 52 seconds off the "standard NTP time", so (assuming the clock was always 52 seconds and assuming Berkeley time is synchronized to "standard NTP time") the time difference is definitely less than 99 seconds.

If I'm not mistaken, that's from the batch of bad WU's which were sent out early in the MultiBeam (MB) rollout. Just abort it.

I am aware that the project scientists and developers are very busy at the moment, but I put foreward a possible server side solution a few weeks ago.

There is an option in the BOINC scheduler code for a longer delay. Other BOINC projects that I run use it.

29/08/2007 12:59:09|rosetta@home|Project requested delay of 242.400000 seconds
29/08/2007 12:59:55|ralph@home|Project requested delay of 242.400000 seconds
29/08/2007 13:00:26|Leiden Classical|Project requested delay of 181.800000 seconds

If SETI and SETI Beta implemented a similar delay, I beleive many more Validate errors could be prevented.

In case someone cares, I am still being plagued by the validate errors. I have switched to 5.9.0.64 Boinc by Crunch3r with latest 2.4V application. I am getting very frustrated.

Hello again..

I have sometimes 'validate errors' too, because of the 'no command' error.. :-( You remember.. ;-)
One week no error, then every day one, two or more.. I think it's a prob with the driver of the LAN-port..
Soon will install a new OS (WinVista 64Bit).. then will see..

Because of your 'validate errors'.. maybe it's the problem that you 'report results immediately'..
I posted it here..

I use BOINC V5.10.13

In Version 5.10.20 you cannot longer report after your chosen time.. it can be last to 24 hours..

Some use Crunch3rs Version too ('report results immediately') and have no probs..
So it's like 'good' and 'bad' - luck..

Me to ever since my computer crashed a few weeks ago. I reformatted the hard drives and had to redownload all the files, including boinc and now all I get is errors. Before when my computer was really slow with junk I was able to dl two at a time, now it does the work and when the time comes I don't get the credit. So, so long folks good hunting I'm a signing off. Don't need the aggravation this bad. Not to mention one guy in our group went from zero points to over 55,000 in a month. Took me since March to get to 9843 so with people like him you surely don't need me! The Vargstr quits in disgust...

There are sevreral possibilities. I notice two different behaviors on two different machines of yours. One of the hosts cannot find a file, and the other is erroring out using an optomized application.

It is entirely possible that you did not configure the optimized application correctly after the re-format, or you grabbed the wrong optomized application. On the host that is failint to start, you are either missing the optomized application or you are unable to download the unoptomized application - probably due to a rights issue.

Errors like these were recognized by the BOINC core client, and are tagged "Client error" in the result pages. They can include bad WUs like this case, errors in the science application, errors in communications, or errors in the core client itself.

When the Validator recognizes an error, specifically when it cannot find a result file it has been asked to validate, the tag is "Validate error". Those are the subject of this thread.
