Hi fellow BSD-types,
I have a buy system that forks lots of processes and I see repeatedly
the message: "Approaching the limit on PV entries, consider increasing
either the vm.pmap.shpgperproc or the vm.pmap.pv_entry_max tunable". My
research suggested that enabling the "superpages" feature via sysctl
vm.pmap.pg_ps_enabled was the best action... that doing so would quite
the warning and improve memory mapping efficiency.
As far as I can tell, however, "superpages" haven't done this -- well,
to be specific, I can say at least that they haven't quieted the
warning. Since I'm still seeing the warning, do I need to tune
something else? Other comments?
System details:
* 8.1-RELEASE-p2 i386 PAE kernel
* 6 GB RAM
Thanks very much!
Charles
