sysctl.conf values reseting

[nocturnal]

Hi

While i had one value(kern.ps_showallprocs) in sysctl.conf all was fine
but then i added a few extra values and now each time i boot i see the
sysctl values in sysctl.conf being reset to their defaults.

This is my sysctl.conf:
------------
kern.ps_showallprocs = 0
kern.ipc.shmmax = 67108864
kern.ipc.shmall = 32768
hw.snd.pcm0.vchans = 4
hw.snd.maxautovchans = 4
------------
