Hi,
Can anyone shed some light on to what the problem is on this WU for me http://www.primegrid.com/result.php?resultid=166293601
I've had a few of these recently, approx. 1 a day.
Any suggestions would be gratefully received,
Pete.

Unhandled Exception Detected...

- Unhandled Exception Record -
Reason: Out Of Memory (C++ Exception) (0xe06d7363) at address 0x750DE124



That's what the program says is happening. There's three causes for this.

The first is a bug in the sieve program. One would expect that this would be happening to everyone if that were the case.

The second is that your computer is indeed running out of memory. This might happen if you're running a lot of programs simultaneously on your computer and/or your swap file space is set particularly low.

The third is that this is a red herring and the problem is something else altogether.

Looking at the memory usage from the dump:

- Paged Pool Usage -
QuotaPagedPoolUsage: 95992, QuotaPeakPagedPoolUsage: 96216
QuotaNonPagedPoolUsage: 5968, QuotaPeakNonPagedPoolUsage: 6032

- Virtual Memory Usage -
VirtualSize: 53391360, PeakVirtualSize: 61603840

- Pagefile Usage -
PagefileUsage: 1769472, PeakPagefileUsage: 9756672

- Working Set Size -
WorkingSetSize: 4509696, PeakWorkingSetSize: 12460032, PageFaultCount: 3309


The last three set of numbers look very reasonable to me. The paged pool (the first set of numbers) I'm not sure about because I've never paid much attention to the pool usage before.

Do you have problems with other WUs failing (especially other sieves), or is it just the TRP sieves? The bottom line is the app is saying it ran of memory, but it's not clear why.

here http://www.primegrid.com/workunit.php?wuid=113290932 you can see another workunit that got "out of memory" errors. I don't know it this is a rare bug or if something got wrong with my computer, but I don't usually have errors while sieving.

Message 22510 - Posted: 14 Apr 2010 | 14:05:01 UTC - in response to Message 22508.

It's not entirely clear what's causing the problem.

Looking through the list of TroubledBunny's failed WU's, only some of them failed with the memory allocation failure. Something else is causing the other failures.

Furthermore, and significantly, other computers have gone on to complete the WUs that failed. This is significant because it proves that the WU isn't at fault.

Now, that does NOT prove that the software doesn't have a bug in it, as the problem could be intermittent and only happen once in a while, even on the same WU. But it is and indication, but not proof, that the problem most likely lies on the TroubledBunny's computer.

I'm not really sure how to track things down further as there's a LOT of potential causes of this. All the things I can think of right now feel like looking for a needle in a haystack.

Michael,
Thanks for looking at this for me.

Currently I'm only processing TRP sieves on that host but I don't recall having any problems with it before. I only use BOINC on it and it's only switched on for between 4 and 12 hours a day.

I've previously used it for LLRing: TRP, SoB, 321, Cullen & Woodall and before that sieving other projects including manual sieving (Primorial) and also AP26.

I'll try switching to PSP and PPS sieves for a while and see how it gets on.
Although I suspect that if I enable PPS sieves that is all I'll get.

I'll post back here in a week or so.

Thanks again,
Pete.

I've not seen any errors since changing so I will simply stop crunching TRP sieves on this host.
Thanks,
Pete
