Been there. Done that. Read sysctl(8) before posting the first time.

# sysctl -a | grep kern.maxssiz
#

No output. Did *you* try your suggestion before posting?

sysctl(8) says:

      -a      List all the currently available non-opaque values.   
This option
              is ignored if one or more variable names are specified  
on the
              command line.
...
      -o      Show opaque variables (which are normally suppressed).   
The for-
              mat and length are printed, as well as a hex dump of  
the first
              sixteen bytes of the value.

-a didn't do the job, and neither did -o, so I asked here.
