While running Rosetta, I believe I'm seeing Windows OS double-faults which are preventing any real investigation. This issue has been happening for a while now -- I'd guess at least 2 months. I thought it may be a particular work unit but perhaps it's a BOINC-related issue -- I don't know.

I leave my machine running overnight and the monitor is turned off. When I turn the monitor back on, there's no video sync. My keyboard lights are not responding to CAPS LOCK so this implies something bad happened on the OS side and has locked up the system.

I enabled Windows kernel debugging over NET and I finally got it to repro; but sadly, I couldn't resync the debugger post-crash -- which means the kernel likely hit a double-fault and that's really blowing up the stack. Either way, Windows isn't able to generate a BSOD (and thus no dump file.) It could be a memory leak issue which also kind of makes sense -- but this would have to be one really big memory leak.

Has anyone else seen a similar issue? This is not likely a random hardware issue as the hardware works fine and I'm ONLY seeing this problem when running the BOINC/Rosetta 4.20 application. The current projects are "pre_helical_bundles_round1_attempt1" "miniprotein_relax10" and "norn_struct_profile_std_layered_design_beta_nocart_w1"

This system has 32GB of RAM and seems far from hitting any maximum limits. Each rosetta process is taking between 425-and 750 MB of RAM.

I have a few more tricks up my sleeve but if anyone can shed light on how to possibly trace the failing project that would be helpful.

It's not Rosetta, it's the system. Be it OS, Driver, other software or hardware. If it were Rosetta, the message boards would be full of the issue- but it looks like you're the only one that is having it.

I'd check CPU temperatures & power supply voltages to be sure, even run Windows Mem tester to make sure it's not a RAM issue (if you have something else with a memory leak, over time the amount of RAM in use will grow till you end up using an address that has issues), but if it's only occurring after periods of system inactivity/ monitor being turned off by the OS i would suspect a possible video driver issue (or video card).
If the monitor is set to power down after so many minutes, i'd disable it and see if that has any effect on the issue.

Grant, yes, it could be an OS issue but Rosetta is exposing it. Either way, I only see the issue while running Rosetta. FWIW I'm turning the monitor off manually. I suppose it could be a Nvidia video driver issue but hard to believe it's only exposed with Rosetta.

The problem could also be exposed depending on how you are using Boinc on the pc ie, on a quad core pc using all 4 cores while surfing, watching videos etc and if you are also running the gpu on a project that takes a large amount of the cpu as well, ie running 2 or more tasks at once or one that uses alot of onboard the gpu memory. All these things put a heavy load on the pc and all of it's components and can cause problems to show up that may not happen at other projects outside Rosetta that may not use as many resources for as long a time.

Running Prime95 for 24hours should cause the same problems to show up https://en.wikipedia.org/wiki/Prime95 a link to Prime95 is inside the article explaining what the program does. This link [url]https://www.tomshardware.com/reviews/stress-test-cpu-pc-guide,5461.htmll[/url is a link to Tom's Hardware explaining how they use both Prime95 and MSI Kombuter to check the cpu and your gpu at the same time. I believe it has links to the software they use within the article.

Running Prime95 for 24hours should cause the same problems to show up...

Well okay so I guess I was wrong. I guess there's some memory issue with my system. I ran Prime95 stress and it failed about 13 hours later. I don't overclock my system and it appears 100% stable in every other way.

Thanks for the help Mikey, Grant. I guess next step is a through RAM test.

Running Prime95 for 24hours should cause the same problems to show up...

Well okay so I guess I was wrong. I guess there's some memory issue with my system. I ran Prime95 stress and it failed about 13 hours later. I don't overclock my system and it appears 100% stable in every other way.

Thanks for the help Mikey, Grant. I guess next step is a through RAM test.

Yes now you need a test that checks each stick of ram individually I would start here and then go further if nothing is found https://www.tomshardware.com/how-to/how-to-test-ram

My guess is you have a stick that intermittently has a problem

Prime95 is primarily a CPU tester.
To test the memory, just use the Win10 Memory Diagnostic, or get a copy of MemTest86.

I'm guessing now that it must be a thermal issue with the CPU. I'll need to check my CPU heatsink. I've run MemTest86 and MemTest86+ (both in their respective OSes) and the memory tests pass.

Or Power Supply issues (Power Supply Unit or motherboard VRMs (Voltage Regulation Modules)).
CPUID HWMonitor is a useful little hardware monitor programme.
