Very interesting read, I think Roger might well find some help there.
I don't think his system is writing the buffers out only once per 30 minutes. It sounds more like a the buffers getting full with data he doesn't need anymore but the kernel does it's normal memory trim, trying to keep as much of it in memory as it can.
It's probably walking some memory structure of the file cache looking for things too empty -- because before it can give the buffers to you it likely has to zero them. What mode are you opening the files in, BTW? Write-only or RW?
fopen with "w+" The file is expected not to exist.
