I have COMPAT_SUNOS committed out:

#options        COMPAT_SUNOS    # Support to run Sun (m68k) executables

I would agree. I upped some limits in the kernels I use:

maxusers        64
options         MAXFILES=8192
options         NMBCLUSTERS=16384
options         DFLDSIZ="(96*1024*1024)"
options         SYSVMSG         # System V-like message queues
options         SYSVSEM         # System V-like semaphores
options         SYSVSHM         # System V-like memory sharing
options         SHMMAXPGS=8192
options         MSGMNB=16384
options         MSGSSZ=64
options         MSGTQL=512

Thanks,
