I press ^Z and type kill -9 % (killing truss). I now have these fine processes hanging dead in memory, they are immune to kill -9 and don't respond to kill -CONT either, ps axl: UID PID PPID CPU PRI NI VSZ RSS MWCHAN STAT TT TIME COMMAND 0 56974 1 0 8 0 1256 744 ppwait D p1 0:00.00 fsck -p / 0 56975 56974 0 8 0 1256 744 stopev DV p1 0:00.00 fsck -p / Is this how things are supposed to be, even though killing a tracer is way stupid? I think it's not nice to have unkillable processes. Is there a way to get rid of these without reboot? Is there anything I can do to help debug this? The software is quite current, half a day maybe. -- Matthias Andree Encrypt your mail: my GnuPG key ID is 0x052E7D95
