I dont have truss on the box to attach to the process and ktrace
doesnt seem to show anything either. Does this sort of hang ring a
bell for anyone ? Looking back at the git logs, a coarse search for
anything to do with mount, doesnt come up with much (2 below). Also
since then a new version of clang so not quite where to start.
Any guidance appreciated. Testing is difficult as the hang doesnt
always happen -- sometimes within a day, sometimes 5 days. ssh is
usually borked as well as some processes. I have a scaled down
telegraf agent collecting some basic stats, and the cpu is pegged at
100%. These are single core devices so not sure what is pegging the
CPU. RAM still shows some available so it doesnt seem to be memory
pressures.
Another data point, in one of the test boxes I have running in the lab,
on the serial console before it became unresponsive, I am seeing
kern.ipc.maxpipekva exceeded; see tuning(7)

Beyond that printing out to the console, I cant do anything with the box
as its not responsive.
