I tried to search, but I couldn't really find anything, probably my search-fu is off.
My core/md hybrid works great when first booted, but after a period of time, maybe a day or two, the playback gets jumpy as if there is a high load average. Looking at the system right now while a movie is playing from external USB HD and jumpy, the cpu use is low, 70% to 90% idle and over 600MB out of 2G ram free. I did notice there are currently 169 local connections either to or from port 3450 (DCErouter), not sure if that's normal or not. It's been up 4 days. I'm not sure if a simple reload of the router fixes it.
It's not an issue with the hardware, after a reboot it's fine, plus it's a dual core AMD BE-2400, 2G ram, nvidia 7300 SE, filesystems all have plenty of space.... Right now that's the only lmce device, no other MDs, no network mounted drives, nothing else I can think of. I guess it could also be related to the external USB drive??? I just thought of that as a possibility and haven't tested.
Any ideas?
