Forced restarts / log out

[lawhochun]

Has anybody experienced forced restarts or log outs on Mavericks? I got it on my iMac 2012 21.5 in base model and sometimes when I am using the system for a while, the OS suddenly freezes and restarts itself, or it logs out of my account then returns to the log in screen.

MacBook Pro 10.9 Unanticipated Automatic Logout

I too am having that same thing happen. When I log back in it reopens most of my applications. This is quite unacceptable. Anyone else having this occur? Any fixes? I have MacBook Pro 2011 13" with 8GB of RAM.

Yes. The WindowServer process is crashing on me with some frequency. Every time it has happened I was pressing send on on email. However, in the crash report I don't see a reference to the mail.app being the cause.

Check your Console to see if it is the same.
