Stanford ran out of work??

[gottcha]

Help what does this mean? I'm in a contest and i can't get any work!:cry::shrug::temper:

[ebug122]

Uninstalling and re-installing the SMP client worked for me.

I dunno if that's the only solution, I was going to re-install it the other day anyway.

[gottcha]

really that suxs. anybody else with a solution? i will have to do something by tonight.

[gottcha]

ok uninstalled and did a reinstall and i get the same thing???????

[torin3]

Some times the servers do run out of prepared WUs, and it might be other problems, like the server may be overloaded.

If you still aren't getting work, you could restart the client about every half hour. It checks several times quickly, then spaces out the requests and waits longer between retries. Restarting the client resets the cycle.

However, if it is because the server is overloaded, you would actually be making it worse by retrying more often. :shrug:

I've got an SMP WU finishing up in the next 10 minutes or so. It is a linux client, so it may be hitting a different server. But I'll let you know if it picks up a new WU.

[gottcha]

Cool thanx for the help. I'll try not to keep restarting the client i don't want to make it worse.

[gottcha]

I tried the restart thing twice and now it downloaded a WU! Thank for the help i guess you were right i think there servers were overloaded...... that means were doing good right!

No need to reinstall the client.

Just stop the client, and restart it, to reinitialize the clients attempt to connect cycle, like Torin posted.

I had a -bigadv WU that was 50% done and I woke up this morning to see the ETA was up to 19 days or so. I checked the log file and there seemed to be some type of error but I was running late for work so I didn't have much time to look into it. I shut down the client and restarted it and it deleted the work and started a new WU. Hopefully this one goes well.

[ChasR]

THe -bigadv WUs have been rock solid on stable machines. If you're having trouble, turn down the OC. If you drop 2 WUs in 10, you get no bonus at all, so squeezing the last few MHz on the OC does you much less than no good.

[Porvalsh]

I get that error when my internet connection is down. For some reason my wireless adapter hiccups randomly and I have to restart to get it working again. Annoying to say the least.

[ChasR]

In this case, the AS reports "no appropriate work server was available". It wasn't a connection problem. The client was actually functioning normally, making the connection, but all the work servers for that particular configuration were busy. Another possibile cause of that message is a configuration error, I don't think that's the case here though. In the old days, if you configured for deadlineless WUs and there weren't any, you got the message. Now days, you'd have to enter less than 64 MB in the memory setting of config.

+1.
I get the same identical log if my network connection craps out on me, which happens a lot on the VMplayer :cry:

I've been folding 24/7 for a month now completely stable @4GHz, I already clocked down from 4.2GHz and that seemed to help. This is the error I saw this morning.

Got home form work tonight and found the SMP client working away. But a check of the log showed after it finished a WU this morning, it took 8 hours to get another one. Grrr. :rain:
Attempt to get work failed, and no other work to do. Waiting before retry.

Same here Giz, I restarted the client but no go. I'll restart VMWare Player as I have nothing to lose after 15 retries. :cry:

Hmm, my retry. No idea of what's happening, hope the WU went through. This on top of my 260 getting half points. sigh That's beta far ya!:D
