Hi, This little bash script might be useful to some: #!/bin/bash NAME=pier_backup VM_PATH=/var/www/pier OPTIONS="-vm-display-X11 -headless -vm-sound-null -mmap 64m" VM="$VM_PATH/vm/pharo-vm-0.15.2d-linux/squeak $OPTIONS" LOOKUP="$NAME*.image" ls $VM_PATH/$LOOKUP -t1 | while read fn do TEST=`ps ax | grep squeak | grep -c $NAME` if [ $TEST == 0 ] then echo "RESTART VM $fn" $VM $fn & fi exit done Stick it in your crontab, and it will automatically restart squeak if somehow it died, using the last backup pier created (image persistency) -- Nicolas Roard "I love deadlines.
