I am starting to see these kernel messages on a busy postgres/FreeBSD box. =46eb 15 23:29:20 pgsql2 /kernel: pmap_collect: collecting pv entries -- suggest increasing PMAP_SHPGPERPROC Lint says about this, # # Set the number of PV entries per process. Increasing this can # stop panics related to heavy use of shared memory. However, that can # (combined with large amounts of physical memory) cause panics at # boot time due the kernel running out of VM space. # # If you're tweaking this, you might also want to increase the sysctls # "vm.v_free_min", "vm.v_free_reserved", and "vm.v_free_target". # # The value below is the one more than the default. # options PMAP_SHPGPERPROC=3D201 What would be a good value for this on a busy postgres box ,dual xeon/2G RAM /100-180 postgres daemons ? -- Micheal O Shea ----------------------------------------------------- com-o-tronic ag Micheal O Shea, Systems Engineer Gewerbepark CH-5506 M=E4genwil E-Mail micheal@com4u.ch Voice: +41 62 887 3734 =46ax: +41 62 896 1133 Internet: http://www.com4u.ch http://www.ehitline.ch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
