I've seen my mythbackend die on a couple different occasions as well.  I 
use mythweb (installed on a separate box from any of my mythtv 
machines), but I'm not sure if it is the sole cause.  If I delete a 
recording from a frontend (i.e. from the "Watch Recordings" section 
after viewing one), sometimes the master backend seems to just "go 
away".  I have the mythbackend process set to log "all", but there is no 
indication of a problem.

Regarding mythweb, I think that it is one of the great features/plugins 
of MythTV -- I use it to do all my scheduling.  However, I've noticed 
that the backend died on a couple of occasions while both scheduling and 
deleting recordings from mythweb.  Again, nothing in the log file to 
indicate a problem.

All myth boxes are running Gentoo (2.6.10-gentoo-dev-sources-r7), and 
mythweb is running on a modified RedHat (2.4x kernel).
