SubjectThe page cache keeps growing
I'd like to throw this out to the group for opinions-

I'm working on a box using the 2.4.9 kernel that is saving a couple of
video streams, while playing back one of them. The box also allows one
web browse, play mp3's and configure one's home network.

What I'm seeing is the page cache grow to huge sizes- to as much as
of 128MB of memory. This is causing pages to be stolen from other
in memory, so that when a user attempts to go to one of these, a long
wait ensues
while it's paged back in.

Is there any way to limit page cache size? I've looked over the mm code
nothing pops out. Has someone written a patch to do this? I've checked
archives but have come up empty handed.
