I don't know if this has anything to do with what you are seeing but recently I had occasion to look at the disk caching code for linux and it turns out that linux will use ALL available memory for disk cache and only release it back to the system under very specific circumstances.
I can post a whitepaper describing exactly what happens and the mechanisms involved in the context of LiS (linux streams) if you are interested.

OK, maybe I sent everyone on a wild goose chase. Somebody tell me if this makes sense:
- Start X, Mythbackend, Mythfrontend, and start to play live TV, all is fine. - Watch memory and it grows to almost max, but mythfrontend doesn't increase. - Stop movie and memory returns to normal. - Start live TV again and let it run. Memory grows to max, then swapping starts.
Is the memory growth due to buffered-up video (which is used for jumping back)? If that's the case, then this is perfectly normal operation. Or, is there a limit on the amount of ram that mythfrontend should consume during playback?
It's starting to sound like my freezing problem is caused by something else? Comments? Thanks, Don
