No patch - but I've got a hobbit-driven script that does the shutdown/restart only if the devmon status message doesnt show up at the hobbit server.

Add to ~/server/etc/hobbitlaunch.cfg

[devmonstatus]
        CMD /usr/local/hobbit/server/ext/dm-status.sh
        LOGFILE $BBSERVERLOGS/dm-status.log
        INTERVAL 5m


Script:

#!/bin/sh

#       Check to see if devmon is hung, and restart if needed

MYNAME=`hostname`
NOW=`date +%s`
DM_STATUS=`/usr/local/hobbit/server/bin/bb ${MYNAME} "hobbitdboard host=${MYNAME
} test=dm fields=logtime"`

DIFF=$(( ${NOW} - ${DM_STATUS} ))

echo " `date` now is ${NOW}; dm_status is ${DM_STATUS}; difference is ${DIFF}"

#       If DIFF is greater than 420 (seven minutes) we'll shut devmon down

if [ ${DIFF} -gt 420 ]; then
        echo "devmon seems to be hung -- restarting"
        kill `cat /var/run/devmon/devmon.pid`
        sleep 155
        /usr/local/devmon/devmon
fi

exit

Hope this is of some help -
