freebsd stable - Oct 2007 - freebsd ipsc -a output missing

I have a generic kernel on my FreeBSD 6.2 system, and I am getting errors
regarding PMAP_SHPGPERPROC which is set at 201 (default).  Because the system is
a heavy load websever, this happens quite often.  I want to calculate the proper
value to to it to, but my ipcs software isn't working.  Anyone know how to
reconcile it?

I do have:

options         SYSVSHM                 # SYSV-style pscshared memory      
options         SYSVMSG                 # SYSV-style message queues
options         SYSVSEM                 # SYSV-style semaphores

compiled into the kernel.

Output from ipcs -a:

mercury# ipcs -a

The default value is 200.

It has nothing to do with ipcs.  The ipcs tool is used to
report SysV IPC data.

I suggest you try increasing PMAP_SHPGPERPROC in your
kernel config, or adjust the vm.pmap.shpgperproc loader
tunable (same effect, but doesn't require building a
new kernel).

Irrelevant.

Obviously nothing on your machine uses SysV IPC, so all
fields are empty.
