Lots of Client errors

(moderation:
Hello, after change of hardware and software configuration I receive a lot of Compute errors in Einstein's workunits (see here). Do you have an idea where could be the problem?
They appear on computer ID 2183839 (AMD Phenom(tm) II X4 945 running openSUSE 11.2 x86_64 (Kernel 2.6.31.5), original BOINC Client 6.10.19 (reports itself as 6.10.17; GPU computations disabled by this trick)). Thank you for your assistance.

Looks like a disk or disk access problem.
I found a
Input file l1_1112.10_S5R4 missing or invalid
and a
Error: couldn't parse symbol information for file name: ��'�D$��7#�D$���&�$������&�t$�$�7#�D$�M

Is your machine overclocked?
The errors look like what you can see if the overclocking is a bit too aggressive or if the machine is overheating (or both).
Cheers,
Gary.

Actually it seems like that, but I don't want to believe it, since my computer behaves stable (I have no problems except KDE4 bugs). My Einstein is running on 1TB Seagate ST31000528AS disk, partition 6, formatted as ReiserFS 3.6. The only known bug related to disk behaviour is some strange compatibility problem of KDE4 with non-UTF8 symbols, but I don't think it has something to do with Einstein.
But, there is one more bug in my system I know about - my motherboard (ASUS M4A78T-E) utilizes AMD SB790 which has a bug with Kingston USB pens... maybe there are some more problem. Do you have some similar reports?
RE: Is your machine

No, my CPU is not overclocked, nor temperatures show any problem. My cores tick on 3GHz and the CPU temperature is 54 degrees C, which is, I think, quite OK.

OK, fine.
The next thing to check is memory. Is it possible to test your RAM with memtest86 or perhaps to try different memory sticks to see if the problem goes away? You could also try doing a surface scan of your HDD at the same time just in case there are any bad sectors.
Cheers,
Gary.

I dit both test and they are OK. I used Memtest86+ 4.00, it did two passes of memory tests and they are both without problem, but their duration is different - the first test took 35mins, but the second took approximately one hour, is it normal?

When I want to test a machine, I have a boot CD that has a range of test utilities. The version of Memtest86 I've used is something like 3.8x if I remember correctly. My recollection is that each suite of tests that represents a pass takes a certain amount of time which is much the same for each pass. I don't know why you saw such a big difference for the second pass.
The CD contains a utility called HDTune which can do a thorough surface scan of the hard disk. Depending on the size of the disk it can take quite a while to complete. Did you do a proper surface scan of the disk? You may also be able to find a manufacturer supplied test tool if you want to exhaust all possibilities.
Cheers,
Gary.

Unfortunately reserfsck does not offer such a choice, so I did only default filesystem check, which was OK. I'll try to find manufacturer's tool.

The Ultimate Boot CD, which I guess is what Gary was referring to, has a number of manufacter's test programs ready for use. It was recommended to me by the trade supplier where I get most of my kit.

Hello, just found this thread and wanted to let you know that I have the same problem and a similar configuration computer ID (Asus M3N78-EM, AMD Phenom(tm) II X4 940, 8GB Ram, Seagate ST3300831A formatted with ext3 and WD1001FALS-0 formatted with ext3, Suse 11.2).
Among others, I get the
Error: couldn't parse symbol information for file name: ��'�D$��7#�D$���&�$������&�t$�$�7#�D$�M
type of error most of the time.
Unfortunately, in a first attempt to fix the problem myself, I ended up with a configuration that doesn't allow me to do any work at all anymore. Upon stating the BOINC manager it doesn't show any of my unfinished WUs or any of the projects I am attached to. Also, I cannot attach to any new projects. The manager seems to try to connect to "localhost", probably fails and stays "disconnected". Installing BOINC in a different location does not fix the problem.
The second Problem is likely to be a configuration problem on my machine, but right now I don't have any clue where or what to look for. Any suggestions?
Thanks,
Michael
