Is this a Boinc problem or Rosetta problem?

All I find is the following in stderrae.txt: *UNHANDLED EXCEPTION* Reason: Access Violation (0xc0000005) at address 0x0032f114 read attempt at address 0x00000008 Now, if this is a BOINC error, it should be noted that I'm still running 5.11, not having come across any overpowering reason to upgrade. This is only happening on one Windows machine, I've got three others all of which run without problems. The one in question is a P4 (Dell Dimension 4700), the other three are two "beige box" AMD 3500+'s and a Pentium M notebook. Any ideas? ID: 30029 · Rating: 0 · rate: / Reply Quote

My first suspect would be memory, followed by the PSU. Memory is easier to confirm though. Memtest86+ is a free download and runs a pretty rigourous test. If you are overclocking you may have to back it down a bit. ID: 30034 · Rating: 0 · rate: / Reply Quote

Ive been monitoring memory usage and I seem to be having a slight memory leak. ID: 30035 · Rating: 0 · rate: / Reply Quote

Were you doing a lot of work on this machine? c0000005 is a common "you tried to read memory you aren't supposed to" bugcheck. Something else may have stomped all over rosetta too.

I didn't start getting those read access violations until 5.32 among other problems. So far Linux hasn't suffered from memory page stomp no matter how busy I get, although memory seems to fill up. I'll see how Linux goes for a week with 5.34. Then I may bring back XP since I do miss the screen saver. ID: 30039 · Rating: 0 · rate: / Reply Quote

Memtest is automagically loaded and run on bootup. ID: 30041 · Rating: 0 · rate: / Reply Quote

I downloaded memtest, unpacked it (Linux) and up pops NERO?!? O..Kay? Yes ... it would be an ISO image. You burn it to a CD and then boot with the CD. Memtest is automagically loaded and run on bootup. If you are on Linux and using one of the common distros, why bother with a CD at all? In my experience the easiest way to run memtest is to ask the package manager to install it. On a networked machine the package meanager downloads it, puts it in the right place, adds it to the boot menu, all by magic. Reboot and select memtest from the boot menu. I have done this on Debian ans SuSe systems. I cannot believe that Fedora would make it any harder. I usually put memtest on Linux boxes as part of my standard install so it is there if ever needed, and it is certainly included on the sets of CDs I've got for installing Debian, SuSe and Gentoo flavours of Linux offline. Some years ago SuSe used to include memtest on the boot menu by default, tho I think nowadays you need to ask for it to get it. Geeks only: If you like creating your own boot menu in lilo/grub just treat the memtest binary as if it were another linux kernel. IMHO The time to think of burning a CD is for running memtest on a win-only machine, or on a linux machine which has lost its hard drive and also needs its memory checking, or on a linux box that is not on the network and does not have memtest already installed.

The errors that 'dgnuff' and 'Keith Akins' have been having are the same as the ones I also have had/am having. The only time I get these errors are when the screensaver is running on 2 of my machines that have graphics enabled. My other 5 machines, both Windows and Linux do not have the problem and have not lost a workunit. So I believe that it is a screensaver issue not a computer issue as my other projects on the same computers do not have a problem, only Rosetta. I hope it has been repaired in 5.34. By the way what happened to 5.33? or did I just miss it? ID: 30051 · Rating: 0 · rate: / Reply Quote

If you really want to know, goto the Rosetta@home testing site Ralph@home http://ralph.bakerlab.org/ and you'll find out. You may even want to attach to Ralph and help in testing.

I just had not noticed 5.33 anywhere (except Ralph) and had not read up as to why it did not make it. Keep smiling, as it makes others wonder what you have been up too.
