OK, I think I solved my problem. I use a script I wrote some years ago (named kpid) to kill tasks by name (at the time, I didn't know that killall could do that)--anyway, I thought my script was using kill -9, but instead it uses kill -15. So now I:
* kill -9 any remaining processes named noatun * kill -9 artsd * then I can restart noatun Sometimes it seems that artsd starts automatically before I start noatun--in the cases when it doesn't, it seems to get started by noatun. Sorry for the noise!
