[mythtv-users] Re: Is this a memory leak?

[Michael J. Lynch]

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.
