I wonder how the peak can be less than the current value.
Normally, it should be current <= peak <= max.

Those numbers are definitely bogus. An mbuf cluster is
about 2 Kbyte in size, so 4292490067 of them would require
about 8 Tbyte of memory. I assume your machine doesn't
have that much memory.

That's 3.3 Gbyte. Also an impressive number.

It's not correct. Maybe there's an API problem -- Are you
sure that your userland is in sync with the kernel?
(I seem to remember that some things have been converted
from KVM to sysctl recently, but I think only vmstat was
affected, not netstat. I'm not 100% sure, though.)
