Validate Errors

(moderation:
I just noticed that my FX8150/GTX550Ti/Win7-64 host has recently generated several validate errors (and "Completed, marked as invalid"). I'm probably missing something in the stderr output, but I don't see much difference between these invalid tasks and the valid tasks for this host.
Any idea what happening and what could be causing the problem?
Thanks,

Oops. I'm seeing the same thing: Invalid tasks for computer 5744895. I did have a few voltage problems with that host before the holidays, but they were diagnosed and fixed, and I've had no problems with it since.
You are having problems with the NVidia GPU version of the Binary Radio Pulsar Search, mine are with the Intel GPU version. I suspect that we might both be suffering from related problems at the server end, but I'll keep an eye on things.

3 errors; one compute error saying
couldn't start app: Input file rand_PAS.bank.v3 missing or invalid: md5 checksum failed for file
two download errors saying that this file was corrupted.
All on the same machine: win7-64, i7, 2 AMD gpu's . Old main win7

Sorry to hear that I'm not the only one...ha-ha. Hopefully we'll get some feedback from the admins soon.
Yeah, but Richard and I are seeing validate errors. :-(

Oh, dear... I might have bigger problems with this host. Every Gravitational Wave S6 Directed Search (CasA) v1.05 (SSE2) is crashing... :-(

Any chance we could get some feedback from the developers or admins on this issue? I've had recurrences since my original post (...and I believe Richard has, too).
Thanks,

Yes, that list looks longer and newer, doesn't it?
Not worth disturbing anyone at this time of night (it must be a small proportion of tasks failing - that host spits out one every 12 minutes, five per hour, 120 per day) - but maybe a PM in the morning.

Hi!
For the host in the thread starting message I see validate errors and invalid results for both GPU and CPU apps, and at a much higher rate than usual. At the same time, other hosts that were computing the same work were able to return valid results (at least in several cases I checked). All this does point to hardware problems, I'm afraid. Using a memory checking tool and checking that the cooling works are standard things you'll want to try first.
Cheers

RE: All this does point to

And I'm afraid you're probably right, HB. I popped the case open and it didn't take long to find a couple of blown components on the motherboard. I'm very disappointed as this mobo is only a few months old. I'll now get to experience my first RMA with a hardware vendor (in this case, ASUS).
Thanks very much, HB, for your feedback. :-)
