I checked all connections, firewall settings (nothing changed) and everything is OK. Server status is Accepting. Already followed "Do this first" topic, it's OK. Help!

Server seems up and running ...

How many processors and memory amount are you reporting ?

Posted: **Mon Apr 19, 2010 3:29 pm**

I think we are suffering from a lack of work units. Based on the FAH-Addict web site, A2 and A3 WUs are in short supply:

Yes, but he has specified -bigadv and as long as he is running Linux, has enough cores and RAM, he would be getting those in preference to A2/A3's.

Posted: **Mon Apr 19, 2010 3:40 pm**

This shortage shouldn't affect the BigAdv server as far as I know (and it's not mentioned as having problems in the news

) : it has more than 2000 WUs ready, and not so much clients connecting to it ...

Posted: **Mon Apr 19, 2010 3:43 pm**

A2 WUs may also include bigadv units since they use the same core. I have one client that uploaded a bidadv WU ~7:15 PDT (90 minutes ago) and it has not yet been able to get a new WU either, and if there was a non-bigadv WU available, I would have gotten one of those instead of a bigadv WU. It is still waiting... and it does say:

"Could not connect to Work Server" and the server IP is 171.67.108.22.

Could be a connection issue or just a lack of WUs at this point.

Edit: 08:47 PDT. Good news. It just downloaded a bigadv WU (2681) and is starting up now.

Thanks for replying. Reporting 4457 MB and 8 cores (Intel Core i7 920). No WU yet. Log with verbosity enabled:

Curious, why the -oneunit flag, and why verbosity 7 instead of 9?

Posted: **Mon Apr 19, 2010 5:03 pm**

I'm running a pre-built vmware image (evga forums). In its custom settings webpage there's a verbosity checkbox that automatically enables level 7 (it's either no verbosity or verbosity 7).
Oneunit is because sometimes I want or need to reboot my real machine and doing that while processing WUs that reward more points the faster you finish them is not a good idea.

Same problem here.

six attempts and counting...

Posted: **Mon Apr 19, 2010 6:19 pm**

I can't understand it. Why isn't another WU is assigned? All this time doing nothing. Things could be changed so that the server is changed after a certain number of attempts...

Still no WU. As the time between attempts increases over time, I have to reboot my machine sometimes.

Posted: **Mon Apr 19, 2010 6:22 pm**

DrSpalding wrote:"Could not connect to Work Server" and the server IP is 171.67.108.22.

Could be a connection issue or just a lack of WUs at this point.

When you have this sort of a problem, the first two steps you should take is to check the ServerStatus page (see the link in our header) and see how many WUs it says it has and try to open http:171.67.108.22:8080 and/or http:171.67.108.22 with your browser. (Use the actual server's IP address, of course.) Most of the time you'll be able to figure out if it's a connection issue or lack of WUs. Then if you're still not sure, ask here.

In this case, there's something strange going on so I'll dig deeper.

Posted: **Mon Apr 19, 2010 6:33 pm**

Did that initially Bruce.
Thanks for investigating.
I just checked server again and same status but now (10:55:10) there are 1762 WU available whereas at 10:15:10 there were only 1705. Weird.

Another machine of mine just finished a bigadv WU and it has same problem.

I've just got a 2683. Thanks for helping!
