In the "Mem" section of the top display, the "buff" number goes up by 24k every 5 seconds (even when you tell top to refresh every 2 seconds). Something's getting buffers and not returning them? I removed the GbE net driver module from the kernel and the problem continues. I'm afraid to remove the sata drivers because I don't want to destroy my raid. I unmounted and stopped the raid, no change. No processes appear to be growing in size, but I'll let it run for a couple of days to see if that changes. Thank you for your suggestion. --Ken S.</body> </html>
