Hi Rod / J?rgen, Looks like you are both seeing the same issue here...

Is this a known problem? > I'm afraid I've not seen it, but we are using the GAMIN, to monitor file changes, and this is using the File Event Mechanism in solaris which is similar to inotify on Linux - so from what you're seeing it would seem that events are being fired at that level first. which then triggers GAMIN, and then the GNOME apps to react. It would probably be very useful to get some stack traces from the offending processes to see if this can confirm where it's all happening. Also, take a look at the gam_server process which is the one monitoring using FEN and dispatching events over D-Bus.
