Hi guys,
a few days ago I had a look at my Rosetta account and I found out, that it generated (and generates) many and many client errors - since December 2012 I had no successful workunit. The output in task details looks like this:

<core_client_version>7.0.27</core_client_version>

I don't see any kind of error there but the result of the task is always Client Error. Unfortunately I cannot find when Rosetta started behave like this, since all recent workunits have this error.

I am running Debian Wheezy 64-bit on a PC with Intel Core i5 3570, BOINC Client 7.0.27:

Can you please kick me where I could try to find a solution?

Today I have let Rosetta calculate another workunit ... again it ended with Client error (see WU558909674). Really no idea what to do with this issue?

Sorry for the lack of response. I'm afraid this section of the forums is pretty underutilized and frequently overlooked.

Looking at your lshw output and the symptoms you describe, two things stand out.

/0/4 processor Intel(R) Core(TM) i5-3570 CPU @ 3.40GHz

and

/0/100/1/0 display NVIDIA Corporation
/0/100/1/0.1 multimedia NVIDIA Corporation

Many users have reported the same symptoms, but the pattern is hard to establish. DK is actively working on it. There is much speculation to the cause, but I'm not sure if we've nailed it down completely yet.

At this point, a possibility is that it is related to NVIDIA drivers; some users have reported success with downgrading. I want to say that it seems to happen only with Ivy Bridge processors, although this could be incorrect. I have been unable to reproduce the problem with my Nehalem i7 and GTX460.

Please see this thread: https://boinc.bakerlab.org/forum_thread.php?id=6177 for the latest. It is mentioned in other threads in under the "number crunching" section as well. Again, sorry for not noticing your post sooner.

Hi,
thank you for your answer anyway, at least I know that I am not alone with this problem. I'll start following the thread you have linked, we'll see how things will continue.

Thanks,
Pushkin
