I'm using kernel 2.6.24 with uClinux and ARM NOMMU patches. When one application starts reading from disk kernel uses all available memory for caching and other applications fail to start (not enough memory). It takes kernel up to 10 seconds to release memory after the first application exits.
Is there any way to limit disk cache size?
