Spontaneous logout while in Snow Leopard

@a.nonymous

Hi, in this case we should check at "System Preferences" -> "Security" -> "General":

There is an option there that says: "For all accounts on this computer:" -> "Log out after XX minutes of inactivity"

It must be unchecked, otherwise Snow Leopard will indeed logout every XX minutes.

I have the same problem of spontaneous logouts in snow leopard. I checked all my settings and that's not the problem. any other solutions?

Have you upgraded to 10.6.2 ? Most users find that has fixed the problem.

10.6.2 seems to have fixed it for me. I've used the various Adobe CS applications without any further log-outs.

10.6.2 hasn't fixed it for me. All I can figure out is that I have it happen when VLC is open and/or Safari open. It seems to happen as I am using the touchpad on my macbook. I hope Apple can pin this down and fix the issue... there isn't even a way to report the error because of the logout instead of a crash.

This just happened to me, and I lost a lot of unsaved work. I also got -

07/12/2009 21:30:37 Finder[180] HIToolbox: received notification of WindowServer event port death.
07/12/2009 21:30:37 Safari[217] kCGErrorFailure: _CGSLockWindow: Cannot synchronize window backing store

Repeatedly in Console. I am running 10.6.2 and was in Pages 09 at the time. Will file bug report for this issue.

FWIW, I have been having this problem ever since I got my brand new Mac Mini in April. It is running 10.5.8, 4mb of RAM. I have Microsoft Office 2008. I also have FileMaker Pro Advanced 10.0v3 and run Firefox 3.5.5 all day long. It always happens to me when in Freehand MX. But I also lose my keyboard control several times a day, either in Freehand or Photoshop CS3. Pulling down a menu item with my mouse fixes that and it is annoying, but not as annoying as the log out.

So, from my experience, this is not just a Snow Leopard issue since I am not using it. I changed my settings in FileMaker to only save cache every 10 minutes instead of during idle time and also am trying to run Entourage without the email schedule checking every 5 minutes and will do it manually for awhile.

I brought my machine in to the genius bar and they did diagnostics on it and found nothing wrong with the RAM or anything else. I have been on the phone with Apple Care a bunch of times on this issue and so far nothing.

I just submitted a bug report. I wish we could figure this out and soon!

dangnabit i just got logged out too. Browsing Safari at the time it happened.

Well, it just happened again. I thought it might be caused by the automatic email schedule in Entourage (MS 2008), but that's not it either. Bummer.

I sure hope we can figure out the problem. All we have in common is that there is a WindowServer port death. It's not even OS version specific!! Grrrrr!

Just wondering...do any of you have Linotype FontExlorer X running?

No,

but I removed Rosetta from my machine, and it hasn't happened since...

That is indeed odd. A number of us had the problem resolve itself with 10.6.2

It's worth checking in Activity Monitor for apps that are running in Rosetta that you may not remember/expect.

I haven't experienced spontaneous log-outs since upgrading to 10.6.2. I don't use any MS Office products. I formerly experienced the problem in Adobe Creative Suite CS(1) but use it for hours at a time without problem now.

I have however, experienced several kernel panics at work... typically while not doing anything noteworthy. Panics are equally bad, but at least they get detected and generate a report to Apple automatically.

This happened to me for the first time today. I've had Snow Leopard since release, and upgraded to 10.6.2 when it came out. I've never had the random logout before, and all that was running was Firefox and iTunes..go figure.

I have the same problem. It looks like VMware Fusion Helper did it. I haven't used VMware in weeks! I was just browsing the web and then it logged out. I don't know if VM uses Rosetta, but I have version 3.0.0 (204229) of VMware.

Let's find a solution!
