My BE on Ubuntu 9.10 did this as well. For me it was an issue with the FE
getting swapped out. I have a quad core system running 64 bit with 4GB of
RAM. I guess as recordings happened Linux swapped out the FE process to make
more room for disk cache. Anyway, I fixed my problem by reducing the
vm.swappiness value in /etc/sysctl.conf.

The line (I had to add) looks like this:
vm.swappiness=10

The Ubuntu default is 60. You can check your current swappiness value by:
cat /proc/sys/vm/swappiness

I think you can also change the value on the fly with:
sudo echo 10 >> /proc/sys/vm/swappiness

BTW my Mythbuntu 9.10 machine is set at the default of 60 as well.

Cheers,
James
