Sorry, never got around to answering earlier, and we were all still looking.

First, a correction: the same thing is happening on C6 servers.

Next, there is *nothing*, not in dmesg*, not in /var/log/messages, to indicate 
when it failed, nor any failure message. No indication why the daemon didn't 
restart it.

* Ok, I've got one good thing to say about C7: dmesg -H. Love it.
