the server just freezes. nothing on the screan. trying to ping the server I realized the server is "crashed".

I posted this "problem" a while ago, and someone told me it is a known bug !? it crashs when you want to start the serial connection (on redhat /etc/rc.d/init.d/serial). it arrived only when you put a cable on a serial port and you do not connect it anywhere. it is beacase "the serial connection is opened" someone told me.
