Hi Ole, you did not (yet) comment the BUG, so I've had a closer look at the reported issue: vmstat 1 2 2>/dev/null | tail -n1 | awk '{print $7*$8}' || vm_stat 1 | head -n 3 | tail -n1 | awk '{print $9*$10}' The idea seems to be "run 'vmstat' and run 'vm_stat' in case 'vmstat' failed". But in

Hi Ole, thanks for the reply. Not quite. True, I am observing the same thing (empty files 12 through 20 below), but what is bothering me is file #11, which has 13 bytes, and could have easily fit into file #10 (1092 bytes) and still been well below the 1200 threshold. Another way to have asked t
