Also, just for a little more information. I was able to cause the
failure while running (mythbackend -v all and mythfrontend -v
all). The kernel ended up killing both the frontend and the
backend. The frontend log didn't show anything interesting.
I can post both of them if you'd like. The backend log showed
this... (even though I shouldn't be using the DVB at the time. No
scheduled recordings till 2pm):<br>

<div style="direction: ltr;">Using SVN 9646. Every once in a while (three times in the last
two days), my mythfrontend goes batty. Once it was idle at the
menu and the backend began recording a show and it went crazy.
And once I was starting mythtv-setup, it brought up the grey G.A.N.T.
background, then went crazy. Both times while just idling at the
frontend menu it began doing tons of disk access and won't accept input
(can't even ssh in). Whatever is happening, it brings the whole
machine to a screeching halt. I can hear the disks going
crazy. I'm thinking that it's a memory leak but the only evidence
I have is a syslog dump (below), it's from the time when I ran
mythtv-setup. I just found that I can cause the "lockup" if I go
into appearances and walk through the menus to finish, when it reloads
the settings sometimes it gets stuck in the memory hog loop.<br>
