The buffer cache will probabloy use as much RAM as you have available,
over time. This is fine, and desirable; it maximises the likelihood that
an attempt to read data will find it already in RAM. If RAM is needed
for something else, any RAM allocated to buffers that have not been
modified (i.e. data that's been read and just kept) can be release for
immediate use.

Really. That's unusual unless your apps are genuinely large. What does "top"
show?
