HI,ALL:


Hello,



My freebsd server offer service to thousands of clients.
I found lots of warning in the /var/log/message like this :Approaching
the limit on PV entries, consider increasing either the
vm.pmap.shpgperproc or the vm.pmap.pv_entry_max tunable



You probably have a lot of processes which use shared memory ..?
Enabling superpages (vm.pmap.pg_ps_enabled=1 in loader.conf) should 
resolve the problem (superpages have been added in 7.2)



My question is :
1.what is the meaning of PV?
2.Although there are lots of this warning,my server works still well.
Could someone explain the meaning of this warning ?
