Volume plugin, gkrellscore and gkrellweather. I have Moon Clock installed, but have never left it running. If I don't leave any of them running, it doesn't normally freeze. Even if I leave the sensor module enabled and running. > > mwm> I've installed gkrellm WITHOUT_SENSOR=yes - which sgid instead of suid > > mwm> - and enabled all the things that I had on when the system was > > mwm> freezing before, except the sensors. > > I'll turn sensor support off by default for workaround. > mwm> I'm not sure that solves the problem.

BTW, I did change the sensors code to open these these files read-only. I know the /dev/io code works that way - I'm using it now - and healthd opens /dev/smb* read-only, so I presume that works. I also caught gkrellscore doing a fetch at startup - even though I had it disabled - including a running perl with read/write access to /dev/io. So I turned on close-on-exec on the things as well. Those things don't solve the problem, but seems like a good idea in general. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
