Pavel, OMJ, maybe execsnoop-bpfcc from bpfcc-tools can help spot what program is starting your dbus-daemons?

Eventually, this results in a 'too many processes' error preventing something to fork, e.g. a login. They get created by batches of 4, every 30 minutes on my box. My box is a puppet client, so that these 30 minutes are not in a local cron tab. The pids are 11 units apart (when the box is otherwise idle). The command line is: //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session ~# ps -fu root | grep dbus-daemon | grep -v grep | tail -8 root 17509 1 0 11:25 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 17520 1 0 11:25 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 17531 1 0 11:25 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 17542 1 0 11:25 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 17972 1 0 11:55 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 17983 1 0 11:55 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 17994 1 0 11:55 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session root 18005 1 0 11:55 ? 00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session I reported this first to https://bugs.freedesktop.org/show_bug.cgi?id=74114 and was told to report it to ubuntu instead. Here were some additional comments: The symptoms you described probably mean that something running as root is either running /usr/bin/dbus-launch, or attempting to access a D-Bus session via the autolaunch: transport while under a transient X11 session, 4 times every 30 minutes. If this machine does not intentionally run an X11 GUI or a D-Bus session, uninstalling the dbus-x11 package or making /usr/bin/dbus- launch non-executable might work around this. Don't do that if you use an X11 GUI environment, though. Since 1.4.8, dbus autolaunch has only been effective when DISPLAY is set and non-empty, so if this is autolaunch, an X11 session must be involved somehow.
