Can anyone explain why I am getting over half of my WUs being returned with a status of "Client Detached"?

I am not manually detaching the WUs. Most of them seem to be detached after about 30 minutes and then I get another two WU and sometimes I get to processes them and other times they also get detached.

The system information is as follows:
CPU type GenuineIntel Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz [Family 6 Model 37 Stepping 2]
Number of processors 4
Coprocessors NVIDIA GeForce GTX 460 (993MB) driver: 25896
Operating System Microsoft Windows 7 x64 Edition, (06.01.7600.00)
BOINC client version 6.10.58
Memory 4087.49 MB
Cache 256 KB
Swap space 8173.13 MB
Total disk space 698.54 GB
Free Disk Space 665.58 GB

List your first 40 lines of your Boinc Manager messages (you can select using click+Shift and copy them), and any subsequent messages relavent to your problem.

When did the problem first arise and is it limited to this project?
Have you any other system with an identical hostname, perhaps a previous installation of Boinc, or did you do a recovery DVD system installation.

None of the other projects running on this system are having this problem. Einstein, Milkyway, Seti and WCG among others are all sending back valid WUs, some of them are even doing GPU work without a problem. I'm not sure when the problem first started but I have been noticing it the last week or so.
This system is a brand new Windows 7 build but it is reusing an old host name. This is the first time GPUGrid is seeing this host name.
I will get the rest of the information you requested this evening when I get home.

Thanks

Is your host attached to BAM!? Looks like the BAM! settings detach your host from GPUGRID.

This host is indeed attached to BAM!

So which BAM! setting is detaching this project from this host? I will check out BAM! and see if I can see anything there.

Thanks.

Do you have GPUGrid on your BAM account?

You might want to ask about BAM over in the BOINCstats forum.

Again yes, GPUGrid is on my BAM! account.

I will do as you suggest and take this to the BoincStats forum as well.

(Of course, now that I am looking at this problem it is behaving itself.)
