It might show something else running or trying to run when you have your lockups. Try "ps -axw -o user,pid,ppid,pgid,tt,start,time,command". 2. Get the PID of the bash session, and run something like this as root: pid=12345 k=1 while true; do truss -p $pid 2>&1 | head -1000 > /dir-with-lots-of-space/$k k=`expr $k + 1` done This should break the truss output into 1000-line chunks and let you clean out the directory before it chews up all your space. Hopefully one of the truss files will show something useful after a lockup. -- Karl Vogel I don't speak for the USAF or my company REMOTE CONTROL - female, because it gives a man pleasure, he'd be lost without it, and while he doesn't always know the right buttons to push, he keeps trying. --from the "What gender are they?" list
