Sudden Logging out

[balkyny]

Hi

Wanted to ask about this for a long time; I do not know what it is,but in the middle of working the screen goes black for a second and I am at the login choices. Then, I enter a password and it logs you in. All the windows, apps that were previously open, start to open.

But the work was gone. THere was no chance to save it.

I can't figure out what this is. I tried to reinstal high sierra 2 times. I can't find logic in this behavior. I work in sound program then open browser and start to type an address then boom - login screen. I tried to find something in system log, but did not know for what I am looking.

Automatic logoff is disabled. I tried enabling it with settings like 999 minutes of inactivity... same!

Any ideas?

That would be loginwindow crashing. I’ve had a lot that with Monterey sadly. Can you update past the version you’re at?

Seriously? This is what it is called? But login window is fine, the crash happens when already logged in and work in progress.

I never had this problem in OS X Yosemite. I am not sure what would happen if I take another step forward. Something may stop working

If you did upgrade to Mojave you would need a Metal supported GPU.

Have you looked in Console after re-logging in to see what flags up?

OK, then I cannot upgrade to Mojave

When you say FLAGS UP you mean in DEVICES section of console? I see yellow dots and red even. Is it what you mean? I never looked there before. GOOD I KNOW NOW. I usually looked in the syslogs trying to figure out how to interpret that information. no luck

So far I see:

Yes I understand. And yeah I believe that’s the name of the process. When it crashes, it restarts and that means going back to the login screen.
It’s just like “re-springing” in iOS, if you’ve seen that before.

Thanks. I will review this now. I also found someting. Check it out.

There is no point in trying the vague 'catch all' solutions like wiping NVRAM and system controllers. The problem you are having is a SIGSEGV, or, a segmentation fault in WindowServer. It is likely due to corrupt identifiers. Those identifiers are stored in multiple places, and if enough get corrupt, you get crashes. While some identifiers are stored in the NVRAM (or PRAM), wiping this usually only postpones the next crash since the identifier eventually ends up in there again.
If WindowServer crashes, all GUI applications stop and it restarts via launchd. When WindowServer starts, it first gives you the login window. So in fact, you are not getting logged out, but your whole graphical session simply crashes.
Having a peek at your crash report, it seems this thread is crashing:
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

The last few calls were to color space functions (or methods), leading me to believe you might simply be dealing with a corrupt ICC profile.
The cash is within com.apple.CoreGraphics, and the most recent calls are to:
color_space_get_md5_digest + 57
color_space_get_identifier + 9
CGXColorSpaceRegistryCopyRegisteredColorSpace + 42
_CGXCopyColorSpace + 27
_XCopyColorSpace + 57

Now, if I'm right, it's trying to calculate the MD5 hash of a color space. It's doing that because it wants to find the identifier for a color space, and it needs that identifier because CGXColorSpaceRegistryCopyRegisteredColorSpace needs the color space data for the preset color profile for your monitor. Now, to be 100% this is the source of your crashes, I would need as many of your crash reports as possible, because if they all crash because of different reasons, it has nothing to do with the software on your system but it's more likely to be a hardware issue where bogus data is fed in to the software which then tries to do something with that data which it cannot do and therefore cashes.
A simple test might be to start Apple's built in ColorSync Utility and pressing the Repair button. This could print something like:
Header message digest (MD5) is not correct. Fixed.

Which would make sense since a broken MD5 might be the source of your crash. So try that first. On my system, that ColorSync Utility is in /Applications/Utilities and I think it has been there since every version of OS X. Please let me know if that found broken ICC files and if it could fix them. If not (either nothing found or unable to fix) please do post any crash logs on WindowServer you have

Geez, it says that it is a problem with memory... I just got additional 8 gb to my 24... so, I need to get 6 chips of new memory? Dammmn.

Right after this crash I found rgis error log. Perhaps someone can figure out what it is?
