As a follow-up:

> Do your error messages look very close to Kyle's (with the invalid
looking date 222yyyy-22MM-22dd 22hh:22mm:22ss.22zzz)?

Yes, indeed!  Searching on 222yyyy was how I found this thread.  It also
seems to happen in the middle of the night.

> Do you all use remote frontends? If so, do you have a real IP address
set for the backend rather than 127.0.0.1?

Yes.  The backend is on an unattended machine that runs the backend, and
a couple of other non-intensive services (Slimserver music server, IMAP
server, DHCP server, DNS server, all for a small LAN only).  It has no
GUI, 2G RAM & 1T+360G HDD, and is not at all stressed!

> Or did you all happen to change a configuration?

No.  It is an Ubuntu Hardy LTS machine that just receives the normal
updates using apt-get once a week.  It uses no special repos (apart from
for the Slimserver).  I have just run mythtv-setup the once, right at
the start.  However, it is not a Mythubuntu install.  It is a server
install with the mythbackend installed afterwards.

BTW, the backend has not gone down since I turned off the jobqueue.
