I have 1.5 GB of memory. Would that make OOM killer unlikely?
About an hour ago, I tried looking at the recorded program's list. The
system froze for about 1.5 minutes then I got a message that it "Unable to
connect to mythbackend, is it running?" I currently have only one machine,
a combined BE/FE.
I looked again at the *mythbackend.log* file. There seemed to be more error
messages there.
