No LL assignments being issued by Primenet.
 
Hey George et al. Just a heads up...

While Primenet appears to have come back a few hours ago, it does not appear to be issuing *any* LL assignments. Neither via the Manual submission form (even when logged in), nor to regular mprime clients (talking directly to the server).

Other work-types /are/ being issued, including DCs and LMH LLs.

submitting TF results in the following error

PNERRORRESULT=3 PNERRORDETAIL=DATABASE UNAVAILABLE ==END==

I'm getting an error similar to swl551's, when Prime95 tries to submit an LL result:

[CODE]
PrimeNet error 3: Server busy
Database unavailable
[/CODE]

For manual submission of TFs, I can log in to the mersenne.org page and see my User Summary, and can even reach the manual results page, but when I try to send the results, nothing happens for a while and then I get a page that's mostly blank except for "[username] logged-in" and the GIMPS artwork at the top left of the page. This particular problem happened last night and then again just a few minutes ago (next time I tried to submit manual TFs).

P.S. When (still logged in) I selected "Totals Overall" under "Top Producers," the page started doing strange things: the left (menu) panel kept popping in and out of existence, and when it's visible it looks different from what I've always seen. And when the page finally stabilized, I was logged out?!

It seems to be fixed now.

This was a strange one. If there are any SQLServer experts here, maybe one can explain what happened.

The SQL statement to get an assignment does a UNION of three "SELECT TOP 1 exponent FROM table WITH (UPDLOCK, READPAST) WHERE some_stuff ORDER BY exponent". These 3 selects get the smallest exponent available for LL, P-1, and TF. The code then returns the smallest of the 3.

What happened was the select statement to get the smallest TF hung. It was my understanding that this should not happen because of the READPAST option. Any ideas?


Anyway, this SQL statement hasn't changed in 5 years so I restarted MS-SQL. I suspect all the LL testers trying to get exponents and getting hung up caused the frequent DATABASE UNAVAILABLE errors.

Fact: (unrelated to the former discussion) The upgrading movement is visible on the server's aggregated computing power [URL="http://www.mersenne.org/primenet/"]graph[/URL]. Going predominantly down for the last 72 hours or so. As people/tools can't report, they delay or give up for a while. Expect bumps and spikes in reports when the "order" will be restored.

Question: (unrelated) What stops replacing the front stats page with the new one? Every time I want to check my stats (/accounts/defaults) I need to input the password many times and this is bothering. As I was in the privileged group who tested that particular page, I know the new one it is working (see my former rant about it). This is just a question. If I am wrong or the things are more complicate that they seems, please ignore it.

The MISFIT tool was having trouble. 3 web pages are awaiting a new MISFIT: accounts, manual_assignment, manual_result

grrr, bark bark woof woof....

who's [URL="http://www.mersenne.org/report_exponent/default.php?exp_lo=31337417&exp_hi=31337417&text=1&full=1"]playing with my exponents[/URL]? (i thought 20 days is a reasonable limit for DC, especially as it was 56% done already! I will finish it and let it count as TC, but in the same time I will take that as "poaching encouragement", so don't ask me in the future "why", if I will)...:smile:

Some Chinese fellow and me.

There is a version of prime95 (v24 or earlier) floating around that was converted to Chinese -- including strings like "is not prime", "has a factor", etc. When this program contacts the server, the server has no idea what to do with the messages and dumps them to a file to be examined later.

Last night, I downloaded the file, recovered some results, and submitted them under Scott's account.

George if you put out these URLs

I can release a hotfix to have MISFIT use the legacy ones allowing everyone else to use the NEW ones (as the default). I can have a hotfix ready today.

:smile: Ok then. No one to blame. We love Mother China. I will finish it and report it as TC. (however, no reason to forcefully "expire" my assignment)
