What I originally wrote indicates that dmesg would get the output: QUOTE In that thread is the message: https://lists.freebsd.org/pipermail/freebsd-current/2018-June/069835.html that has a patch for dumping out more information to demsg before it does the kill END QUOTE (More accurately: the output goes to where dmseg gets what it reports. I tend to use dmesg -a .) The original Mark Johnston message said: QUOTE The patch below prints a few stats to the dmesg before the kill. The output of that together with "sysctl vm" output should be enough to determine what's happening. END QUOTE === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
