I was looking at my old WU (wating for validation or what else for more than 6 months) and see some let´s call "wierd validadted WU", and example:

http://setiathome.berkeley.edu/workunit.php?wuid=1265541696

The first task, was running and exit normaly, the secon one runs for seconds and exit in an overflow, and the third one ends on too many exit error.

The question is why the validator validate work like this?

Is just one of the several old WU some validated and some no for more than a year waiting for? Can´t imagine what some have more than 2 years and still waiting... just a waste space on the DB.

If we are actualy looking for one "golden WU" (the ET call) in the entire millions of WU, then things like this could make us loose the "golden WU".

The date looks to be around the same time that Eric ran his credit granting script which let many of these bad results through.

Cheers.

Could be but, then why the DB was not cleared after all this time? Need some time to dig more examples but i´m sure it´s something very common (at least on my hosts).

Or other example compleately diferent example:

http://setiathome.berkeley.edu/workunit.php?wuid=967420872

In this case, the WU were validated and one task still waiting for validation?
Date May/2012. Each each one has few of them will be thousands of WU waiting for what? an "infinite time validation".

or like this: http://setiathome.berkeley.edu/workunit.php?wuid=1252882786 actualy validade but never cleared from the DB for almost a year.

If the DB size is a issue this only could contribute to make the problem even bigger.

Those in among the tasks stuck in limbo that for whatever reason didn't get cleared out when they should have been. It happened with the previous version of AP & it is now also clear that it happens to MB tasks as well. I have 22 SETI@home Enhanced tasks stuck in suck odd states.

It does seem to be a general issue with the BOINC server which I would not expect to be fixed any time soon.

If DB size is a serius problem as noticed (and the main reason why we still have the 100 GPU WU limit in place) and each one of us has, let said a random number 5, with 100K users we talk about 500K WU doing nothing on DB...

If nothing was made to fix that then something sounds wierd no?

BTW Wiggo i find the issue exactly because i have some host i want to delete from my list as you.

@Hal9000 I like the name you give - added it to the thread title.

I do not think the issue with the stuck stats is nearly that bad. IIRC when AP v5 ended there were only a few thousand stuck. Which did get cleaned up in time.

However it require Matt or someone in the lab to write the clean up script & run it a few times. It is a bit annoying to us, but from their point of view probably does not effect the project enough to warrant any action. Given that I have stuck tasks that go back as far as 2010 I wouldn't expect it to happen soon. Unless there was a reliable funding source to fund a person to do random clean up like this for them.

I still show 119 Enhanced tasks hanging around in my results.
118 validated and 1 error.
The error task is shown as abandoned. In November of 2010.
