I've had this crash twice in the past with a Dell box running Fedora 5.
Recently the same crash has occurred under a homemade box utilizing Mythdora
4.0 with mythtv updated for schedules direct (0.20.2 ).
 
The symptoms seem to be similar.  The database was updated and about an hour
later some recordings were started. Attached is the output from the log.  If
I recall (from last time) it seems to occur on days when a last minute
schedule change was made.  In the last case games 5 through game 7 of the
world series programming was changed.  I don't know if this has anything to
do with it but it was the only difference from other days.  Both these
systems have been running daily for over a year in total.
 
My system consists of 3 - Dual tuner PVR-500 cards and a MS USB2 IR box
