In the mtr defaults # that long message buffer memory has been reduced from the default 64MB to # 4MB and as a consequence data nodes will fail to start due to out of long # message buffer memory. The number of cpus are reduced to 16 to allow data # node to start with reduced long message buffer memory. NumCPUs=16
