Damned ... I Hate it when i have to keep replying to my own emails within 10 minutes after sending them. It looks like i was able to trace down the source of the steadily increasing amount of "devbuf" usage. I opted to simply shut down any port-installed daemons to make sure there was no software running besides the FreeBSD base-system (and a zsh). And through that i managed to find out that the process that seems to be responsible for the steady increase in "devbuf" usage is "hald". As soon as i stopped hald the amount of "InUse" memory of type "devbuf" remained stable over more than a minute. As soon as i started hald again the increase resumed by 140k every 10 seconds again. I'll try to leave the system running now with hald turned off to see if the memory problem persists (after a fresh reboot devbuf usage seems solid at 4254k). As a precautionary measure i'll probably try to take this hall issue to the FreeBSD-GNOME team to see what they have to say about this :) I'll keep the list posted on any further details, but it looks like this may have been a false alarm.
