I was just pondering recently as to what the acceptable levels of size and
amount of mbufs in use are. I vaguely seem to recall that if you run out
of mbufs, the machine will either panic or reboot. My reason for asking is
simple:
root:ninbox: {13} netstat -m
767/1152 mbufs in use:
509 mbufs allocated to data
258 mbufs allocated to packet headers
503/846/1024 mbuf clusters in use (current/peak/max)
1836 Kbytes allocated to network (60% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
Yet I do not ever see this machine as a risk for running out of mbufs.
Most of my machines have much lower mbuf usage (at the moment). I guess I
am more interested in finding out what the acceptable load levels are and
how to increase them, up to a non-ridiculous level.
