PV entries too small

[Michael Zach]

Hi,

I get an "Approaching the limits on PV entries, increase the 
vm.pmap.shpgperproc tunable." all the time when the system gets under 
heavy load.

System was build on April 8:

FreeBSD bender.intern.foobar.com 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Sat 
Apr  8 09:54:44 CEST 2006     
zed at bender.intern.foobar.com:/usr/obj/usr/src/sys/BENDER  i386

Searching the lists and google'ing around didn't show much results, 
except the implementation sources. Also it seems to be impossible to set 
this via sysctl during runtime nor does it show up in sysctl -a.

Didn't try setting in using loader.conf yet since I haven't found a 
reasonable value documented.

Thanks,
Michael
