Very, very weird. You all seem to have some weird issues with dbus-daemon that I don't have. (times retrieved with ps axS, memory consumption retrieved with htop) On my 77-day uptime server runing Debian 5, dbus's total time is 0:00. (That's with ps axS) virtual memory of 21M, resident of 900K. On my gentoo desktop, 8 days' uptime, I show two dbus-daemon processes, both with 0:00. Both with virtual of 19M. One with resident of 984K, one with resident of 808K. On my router, Debian 6, with 4 days' uptime, ps axS shows 0:00 for consumed time. 23M virtual, 968K resident. -- :wq
