Error 0X12

Postby MoneyGuyBK » Sun Dec 02, 2007 7:48 am

Please read/look at message number 2090 here: (I edited to correct the link with snips 12/02)

Ok, I am going to try to see if there are any Linux/Ubuntu Gurus who can help me solve my issue.

I am a member of Folding@Home thread. Team Number 80856, Team name Team XPS

As a group we all have tried different setups to increase our WU & Point production.


We all started with graphic folding clients, and eventually moved up to SMP_Clients.
When I used Windows_SMP, all was fine, and with the exception of an issue with one particular WU (2652) I had no problems.


I then moved to a Linux SMP_Client.
At first I used VMWare Workstation free trial for 30 Days to run Ubuntu. With the exception of a few lockups, I encountered no real issues.

After the 30-day trial, I switched to their free VMPlayer.

At first all was fine, I folded well over 8 dozen WUs with no issues.

Lately, I have had more than a dozen Linux_WUs finish to the end and when the client tried to upload them back onto the Stanford U's servers, I got an Error 0x12 and the client deletes the WU, and downloas a new one.

This goes on now almost every other WU, or I might load 2 good WUs and then the issue comes up again with the next one, and goes away with the one after. The only thing that comes to my mind is that maybe the free vmplayer has issues, but now others are reporting issues on Team_XPS.

*SO, with my apologies for being long-winded here.
The questions are: What is an Error 0x12, and what might cause it, and how can I fix it???

The link above takes you to Team_XPS Thread here on DCF, where I have posted 3 screen shots of the issue. I had to do 3 shots to get the end of a WU in the first snip, and the the client uploading and starting the next WU in the 3rd snip.
If you scroll to the second Snip I have posted there, the Error 0x12 is given there.

Any suggestions, and most important a solution to this issue is greatly appreciated by yours truly and Team_XPS.



Peace

My Current Setup:
Dell XPS720H2C, QX6800 OC'ed to 3.73 Factory Settings
* I have even tried it with lower OC levels, same error occurs.
Running Windows Vista Ultimate, 4Gig RAM
Running VMPlayer and Ubuntu, Folding with Linux_SMP

You may want to check out the FahWiki, of particular note for such a fatal error;

"This error occurs if the (SMP) client is started but the files of the current work unit (as registered in the queue.dat) have been deleted."

Also, please consider using a non-animated gif (and smaller) avatar. Be kind to those folks with less bandwidth piplines. :) Thanks.

Out of all your links, the only one which works for me is the last one. It's probably best to post your data here. You are linking to some areas which require registration.

I can answer the first part (What is an Error 0x12) from FAH Wiki:

http://fahwiki.net/index.php/CoreStatus_codes

Fatal
12
Error: Could not write local file. Exiting.
- Shutting down core
CoreStatus = 12 (18)
Client-core communications error: ERROR 0x12
This error occurs if the (SMP) client is started but the files of the current work unit (as registered in the queue.dat) have been deleted.

Hopefully, somebody else with a similar experience can help more.

Edit: Sorry for the echo. :)

Giving this some more thought. Please realize that SMP clients are still in beta. Someone may have told you beta will yield more points, but I think you are realizing that may just not be something you can take to the bank. If point yield is the primary goal, you are probably better off sticking with non-beta clients and work units. You may feel the points per day are lower, but if you are not continually seeing the WUs deleted ...

It is usually best to leave the beta work to those whose primary interest is improvement of the process. Trust me, those guys definitely know how fast they can lose credits doing beta testing. :)

Error 0x12 is often a result of a permissions problem. For example, if you've run the FAH client as root and then switch to a non-admin user, the client may not be able to overwrite the files owned by someone else. You might also have problems if the disk fills up or reaches your quota, but that's less common.

The client must have full read/write permission to all of the files in the local directory in which the client is installed.
