I have freeBSD 7.0 and get a lot of these messages:
Code:
Jun 12 01:00:01 bsd kernel: Approaching the limit on PV entries, 
consider increasing either the vm.pmap.shpgperproc or the vm.pmap.pv_entry_max tunable.
howto solve this problem ?

What is the output of
Code:
# sysctl vm.pmap.shpgperproc
# sysctl vm.pmap.pv_entry_max
You could set these to a higher value. There probably are also sysctl variables which tell you how much of these maximum values you are using now.

I don't have access to a FBSD box at the moment so this is all the help I can give you at this moment

See the man pages for sysctl and syscontrol.conf

I tried to change, but it doesn't work:
Code:
# sysctl -a | grep vm.pmap.shpgperproc
vm.pmap.shpgperproc: 200
# sysctl -a | grep vm.pmap.pv_entry_max
vm.pmap.pv_entry_max: 448896

# sysctl vm.pmap.shpgperproc=400
sysctl: oid 'vm.pmap.shpgperproc' is read only
# sysctl vm.pmap.pv_entry_max=8000000
sysctl: oid 'vm.pmap.pv_entry_max' is read only

Maybe the securelevel is preventing you from setting these. But because of a house move, I don't have a FreeBSD system available to give you further assistance on this.

I suggest you google at http://google.com/bsd for vm.pmap.shpgperproc
