I did have this problem once in a great while under Redhat >4.2, but this is far to frequent to be tolerable. I had something similar happen, and posted a message a while back but got no replies. I ended up determining that the file /etc/diald/chat.fifo (in diald version 0.16.4 if I recall the number correctly) was the problem. It would get to about 4k in size, and then the system would stop responding to commands, just as you described. Only difference is that I found a Ctrl-Alt-Del was another valid method of rebooting. To patch around it, all I had to do was issue a 'cat /etc/diald/chat.fifo >/dev/null' and let that process run in the background. (I ended up making it start from rc.local so I didn't lose a login screen to the command.) A better fix is the most recently released version of diald. It eliminates the chat.fifo file, and uses only the dctrl.fifo file. Unlike the chat.fifo file, it does not get "full" and cause lockups, and the diald graphical monitor program (dctrl) is nifty in XWindows. Only comment is I wish it could resolve the IPs into names... >From another post a while back...
