Well, speaking for my machine: serving some nfs dirs from zfs, do some file transfers via rsync/scp, server some web pages (gitweb, redmine). Really nothing spectacular. I just updated from 7.2 to 8-stable yesterday and did not have that problem before. From my last email to now (about 15 minutes) mbuf clusters have increased from 15k to 18k. All my other machines (even another one with 8-stable, but without nfs-services and without em nics) have only a few k of buffers in use. Is there any way I could find out what is actually using these buffers? cu Gerrit
