Now after some additionial investigation i have come to the realisation that the most likely source of the problem was because according to vmstat -m the "InUse" statistics for the memory type "devbuf" were consistently increasing by about 140k over a 10 second time peroid. I decided to shoot down any daemons originating from port-installed software to ensure the problem was indeed caused by some part of the base system and not some 3rd party influence and i managed to trace the problem down to hald. Whenever i halted hald the increase in devbuf-usage would halt (not decline simply stay at the same value), and as soon as i started hald again the increase would resume with the 140k/10s ratio until hald was stopped again. If anyone in the FreeBSD-GNOME team might have any idea with regards to what may be causing this problem i am more than happy to cooperate in trying to resolve this issue. The system in question is an AMD Athlon64 3800+, 2GB RAM using an MSI K9N-Neo (nVidia MCP55-based mainboard) running FreeBSD/i386 8.0-CURRENT as of April 16th late afternoon CET. With kind regards, Pascal Hofstee
