texte = Hi All, Very rarely(once every couple months) I have WebDNA 6.2 stop, and drive the CPU nuts on Snow Leopard Server, and am looking at adding a script to keep an eye on it while I go on vacation. I found an old script... not sure where it come from or where I got it, but I had it on one of the old servers, and would like to get it working using launchd to start it, which isn't the problem. When I trigger the script, it comes up with "ps: No user named 'x'". Which is fairly obvious to those who no about these scripts, which I don't. So my question is, does anyone know how to get this working, or is there a better way? ... Script below. Rob #!/bin/sh ## Threshold of CPU % activity ## CPU_LIMIT=145; ## number of times in a row this threshold must be reached ## THRESHOLD=2; ## time between checks ## SLEEP_TIME=5; ## Other non user-edit stuff ## COUNTER=0; AGAIN=0; while true; do { LINE=`ps -aux | grep 'WebCatalog -m' | grep -v grep ` CPU=`echo $LINE | awk '{print int($3)}'` #echo "cpu "$CPU; #echo "n_times "$COUNTER; if [ $CPU -gt $CPU_LIMIT ]; then COUNTER=`expr $COUNTER + 1`; if [ $AGAIN -gt 0 ]; then # echo "again "$AGAIN; if [ $COUNTER -gt $THRESHOLD ]; then PID=`echo $LINE | awk '{print $2}'` date kill -9 $PID COUNTER=0; AGAIN=0; fi else ### [ AGAIN == 0 ] AGAIN=1; fi else ### [ $CPU lt $CPU_LIMIT ] AGAIN=0; COUNTER=0; fi sleep $SLEEP_TIME; } done
