Looks like you have an up-to-date kernel. What do you have MAXUSERS set to?
Also, I'm sure that this just shows my ignorance, but how can it be the case
that the load averages are 67-46 when the CPU is 70% idle? Those two figures
seem to be at odds with each other based on my experience.
As for panicing, yes, one would hope that userland would get load failures
and application failures before the entire system goes to pieces.
In this case it looks like it can't create an entry in the virtual memory
table (I mean, that's what I'd guess that name does) . . . I think that you
might need to bump up your
# Change the size of the kernel virtual address space. Due to
# constraints in loader(8) on i386, this must be a multiple of 4.
# 256 = 1 GB of kernel address space. Increasing this also causes
# a reduction of the address space in user processes. 512 splits
# the 4GB cpu address space in half (2GB user, 2GB kernel).
#
options KVA_PAGES=260
But this is mostly an UNeducated guess.
