xorg server config

After new installation of Slackware 12.1 I have 100%cpu X freeze randomly or I can reproduce it via for example press "logout" in icewm menu.
Screen is freezing, I can move mouse cursor but without any interaction, keyboard dosnt respond on any action.


After freeze strace on X show:
11:51:28 --- SIGALRM (Alarm clock) @ 0 (0) ---
11:51:28 sigreturn()                    = ? (mask now [])
11:51:28 --- SIGALRM (Alarm clock) @ 0 (0) ---
