Approaching the limit on PV entries
hi
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. |
|
|||
What is the output of
Code:
# sysctl vm.pmap.shpgperproc # sysctl vm.pmap.pv_entry_max 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

Code:
# sysctl vm.pmap.shpgperproc vm.pmap.shpgperproc: 200 # sysctl vm.pmap.pv_entry_max vm.pmap.pv_entry_max: 448896 |

See the man pages for sysctl and syscontrol.conf

Code:
# sysctl kern.ipc.shm_use_phys=1 |

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
