i've been in osx for three weeks now, np.
just now...
opened a couple of apps, playing a song in itunes,
my powerbook screen blinked, then logged out (returning me to the login screen).

what could cause this?

(and what, if anything, should i do about it??)

thanx!

Glad to see it's not just me. I've had 3 in the last 2 months.

Never saw it in a year and a half of X on my Pismo. Only started with my new 12" PB.

Each time has been shortly after waking up the computer. Hit work, wake it up, plug in power ethernet and USB mouse. a little later....boom. Login screen

hmmm...AM on a pismo! but first time this happened.

btw, isnt it NOT a good idea to plug usb stuff in while running? (just wondering...)

anyone else getting sudden logouts??

loginwindow probably died.

That's the parent process of everything you're running. If that dies, almost* all other processes you're running from the console will die as well.

* There are, of course, exceptions to this, but these are beyond the scope of this post.

USB is hot-pluggable, so this is supposed to work fine.

oops! i thought firewire was hot-pluggable, and usb is not.

thanx 4 info..

Hi,

I'm on a pismo and i've had it logout unexpectedly once on me. It's been fine since then, I guess it must have been the loginwondow process as someone mentioned earlier.

both are hot-pluggable, you just need to unmount the corresponding media before you unplug the cable.
that's it

Wierd things were hapening on my G4 similar to this and trashing the loginwindow prefs fixed it.

This was one of the symptoms of the bad RAM piece in my B/W G3.

That's just the ol' SystemUIServer. Fickle beast she is. Y'arrrr....

...Somewhat related.

I don't think this is unique to OSX. I'm running Red Hat 7.2 on some PC's, and there is a particular open-source Batch Scheduler I use that regularly causes unexpected logouts.

I had this problem as well. It turned out to be bad RAM. After removing it everything was fine.
