Since gnuplot was spinning in kernel mode, all bets are off. This timeout is most likely a side effect from that, unless you see this every reboot not just with an unkillable gnuplot. If your system has the ability to run procstat -k, you might find out what gnuplot is spinning on. You'll need at least a 7.x system, but I'm not sure if kernelthreads are supported on ia64 and kernel needs to have STACK or DDB options. -- Mel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

It could be that the process is stuck in the 'D' state (uninterruptable wait). You can veryfiy that by running 'ps -u' and looking in the eight column when gnuplot is running. Does the window with the plot actually appear? Interactive use of gnuplot-4.2.6 is fine on amd64 7.2-RELEASE-p2.
