	I am not sure that this works as intended. The first thing run.sh does is take down all running SQM instances:

PROTO_STATE_FILE_LIST=$( ls ${ACTIVE_STATE_FILE_DIR}/${ACTIVE_STATE_PREFIX}* 2> /dev/null )
for STATE_FILE in ${PROTO_STATE_FILE_LIST} ; do
    if [ -f ${STATE_FILE} ] ;
    then
	STATE_FILE_BASE_NAME=$( basename ${STATE_FILE} )
	CURRENT_INTERFACE=${STATE_FILE_BASE_NAME:${#ACTIVE_STATE_PREFIX}:$(( ${#STATE_FILE_BASE_NAME} - ${#ACTIVE_STATE_PREFIX} ))}        
	logger -t SQM -s "${0} Stopping SQM on interface: ${CURRENT_INTERFACE}"
	/usr/lib/sqm/stop.sh ${CURRENT_INTERFACE}
	rm ${STATE_FILE}	# well, we stop it so it is not running anymore and hence no active state file needed...
    fi
done

before diving into the individual coin fig sections. And all instances that were stopped better be restarted unless their configuration changed. (The current SQM scripts allow multiple concurrent active instances,it would be nice to keep that capability).

Best Regards
