    Please post in this thread.

    Please leave behind the following data:

    • On which unit did it happen? (See in your Your Account, Results.)
    • Which operating system are you using?
    • What make & model of CPU do you have? Is it overclocked?
    • How much memory does your PC have?
    • Did you get the crash when you had graphics/screensaver on?
    • What make & model videocard do you use?
    • Is it updated to use the latest DirectX and drivers?
    • Do you have Microsoft .NET installed on your computer?
    • Are you using the latest BIOS/drivers for your motherboard?
    • Which BOINC version are you using? (if need be: And why?)
    • How is BOINC installed? As a single/shared user install or as a service?
    • Are you running multiple projects? If yes, list them and tell of the switch between projects time and if you leave the applications in memory when preempted.
    • When did the crash occur? Did you reboot, was it when changing projects, something else?
    • What do you think crashed the Albert unit?

    For me it was:
    - this is one of the 9 I had.
    - Windows 2000 SP4.
    - Intel Celeron 2.3GHz (stock speed).
    - 512MB PC-133 RAM.
    - I don't use the screensaver or the graphics.
    - Ati 9600 Pro 128MB.
    - Using the last pre-dotNET drivers 5.10 with DirectX 9.0c ..
    - No.
    - Yes to both.
    - 5.3.6. Alpha (I am a BOINC Alpha tester)
    - Service by standard. Now running it manually.
    - Yes: Einstein, Seti, Seti Beta, LHC, Pirates, Primegrid.
    - As far as I can find, it occured after I rebooted. BOINC was running as a service at the time.
    - I think I had some kind of memory problem. In my case the result was trying to read from the top of the memory stack. Weird after a reboot, but not unthinkable.

    ----------------------------------------
    I am posting this survey on my own. I hope to get to the bottom of it by running debugger programs with the help of Walt, Bruce and Bernd, but more information from you out there would help.

    If a moderator could please sticky this post?

    If the developers (or I or other helpers) will have additional questions we'll post them. Please keep this thread clear from any other errors.

      This is the section prervios to the crash and right after.

      I had the Bionc screensaver on. I've been running strickly BIONC on this system at night I kill all other no-esential srvs and programs. Itry to set it to a blank screen but I forgot last night.
      Graphics: Matrox Parhelia 128, latest GPU bios and driver set.

      .Net :Installed latest version as of 2/1/06
      Bios: up to date.
      The curreent release of BIONC being 5.2.13
      BIONC is installed as a servive
      I am running Seti and ClimatePredictions as well as the Pulsar study. The switch, happens quite smoothly as I can see. I have no data to suggest a problem at the moment within the swith of programs. I don't know if the code has a hard time with multithreaded environments, I would doubt it but just a thought. (as in multiple CPU's or virtual CPU's) I original took it as 1 badly coded module. Now, I've sen that many of the mod's sent out are crashing not only on my machine but many others as well. I woould think that the main codeing for this type implementation needs to be readdressed but that is and opinion of someone who has very little data to base any statements on.

        I shall answer these questions best I can...

        It happened on at least two results
        I am using Windows XP with SP2
        Celeron processor 2.6ghz Overclocked: Dont know
        256 MB RAM
        Not sure; the most recent one appeared to have done so: result 17292647
        Not sure how to find out my videocard type
        Should have the latest directX
        Microsoft .net?? Never heard of it
        Not sure if i have latest BIOS setup
        Version 5.2.13
        Single user setup
        Not using multiple projects
        The most recent one appeared to be when it went to the screensaver
        What do I think caused the crash? I have no experience in computer programming so have no idea!

        edit:graphic driver appears to be Intel(R)82845G/GL/GE/PE/GV graphics controller

          I post also in this thread my stats, if they are helpful. I have opened a new thread for trying to fix ***UNHANDLED EXCEPTION***
          http://einsteinathome.org/node/190775

          I suppose so, but not sure

          Intel 82865G (built-in videocard)

          SETI (100)
          [*] When did the crash occur? Did you reboot, was it when changing projects, something else?
          I haven't got a work unit finished for almost 2 months, more than 10 work units went to the trash. So the answer to this question is quite complex: reboot or changing projects? I don't think so.
          [*] What do you think crashed the Albert unit?
          Obviously a not valid access to memory

            Quote:
            0xC0000005 errors, or Access Violation, means that the program tried to access memory that either didn't belong to it, wasn't allocated, or was a write operation to write-protected memory. Could be anything that caused it, often its running past the end of a table or using a pointer that doesn't point to valid data.

            That's what Walt wrote me in email. So we do now know what it means, but there's no solution to the problem yet.

                  Wilfred,

                  I have a nagging hunch that your computer has a memory problem. In most of the errored WUs, it stopped at between 28.5 and 29.5 minutes into computation, probably at the same instruction.The time variance is close enough to be the result of other varying computer activity.

                  If you'd care to check this, you can ..

                  1) Download and run memtest86. In order to give it a good test, I suggest you run memtest while running another intensive program, such as Seti, at the same time.

                  or, ...

                  2) To prevent electrostatic damage to delicate parts - Be very careful to ground yourself to the computer case while touching anything inside the box. Turn your computer off, unplug it, open the case, and swap your two sticks of RAM, one into the other's slot, and vice versa. Then Button everything back up, restart, and run Einstein again.

                  Michael

                    Michael,

                    I see your point but I doubt it's a hardware problem... the 0xc0000005's first started coming on my old office box about 2 months ago, but now I'm running a brand new one ;-) and having mem probs on both seems unlikely (but possible); other prob is that these days our office boxes have no floppy drive, and for security reasons we can't boot them from USB devices either - so no memtest.

                    I'll try swapping the RAM one of these days, will keep you posted.

                      I found a memory test that runs under XP (HCI MemTest 3.3), and let it run overnight.

                      Result: 3128% coverage, 0 errors.

                        I got this error too and already postet about it here.

                        Ok, other details:

                        When did the crash occur?: The host was not used at that time.
                        What do you think crashed the Albert unit?: There might be a wrong address calculation, that refers to a forbidden part of the memory:

                        ***UNHANDLED EXCEPTION****
                        Reason: Access Violation (0xc0000005) at address 0x0040AABD read attempt to address 0xFF7455C8

                        1: 04/20/06 14:32:20
                        1: e:\\einsteinathome\\cfs\\windows_build\\albert4.37\\cfslaldemod.c(941) +7 bytes (TestLALDemod)

                        Isn't that memory part close to the top of 4GB? There may be IO-areas for PCI-devices.
