X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 07 Mar 2007 16:21:15 -0000 Heavy Apache usage is demanding a higher PMAP_SHPGPERPROC kernel option in my system. However I keep getting the NOTES-documented panic at boot time, meaning I need to adequately do vm.v_free_min, vm.v_free_reserved and vm.v_free_target sysctl tuning. However, this sysctl vars dont have a description and I simply can't find any further documentation regarding how the vars relate among themselves and how they related to PMAP_SHPGPERPROC. Can anyone please explain some basics about how they relate and how I can do the tuning? It is a 5.5-STABLE with 9GB of memory and PAE enable (sure). Hackers' feedback or sysadmins' personal experiences are heavily appreciated. Sorry for cross-posting, I was not sure which list was more adequated. -- =========== Eduardo Meyer pessoal: dudu.meyer@gmail.com profissional: ddm.farmaciap@saude.gov.br
