[mythtv-users] frontend and backend crash cause by kernel paging?

The frontend and backend crashed simultaneously on me today.  This was 
unusual because it was the first time that it has crashed on me while 
viewing a recording (of course it may have been recording another show 
at the time, not sure)

var/log/messages had this to say about the incident:

And 2 more entries almost indentical

Any ideas on how to prevent this from happening again in the future?
