I've tested our LAN when I come to this:
I ran nbtscan 192.168.0.0/16 after a 2-3 secs kernel started printing
"All mbufs exhausted, see tuning(7)".
if you cancel execution of nbtscan - everything is ok but:
10112/10112/10112 mbufs in use (current/peak/max):
9822 mbufs allocated to data
128/130/2528 mbuf clusters in use (current/peak/max)
2788 Kbytes allocated to network (36% of mb_map in use)
161 requests for memory denied
0 requests for memory delayed
8 calls to protocol drain routines
and second after kernel paniced.
After reboot tried this again and nothing has happend.
Then I mounted a NFS directory exported from the other computer on the
network and tried nebtscan 192.168.0.0/16 again ... and kernel paniced
when I execute "ls" in the NFS mounted directory.
Fatal trap 12: page fault while in kernel mode
.
.
.
current process = 272(ls)
...
I can't use this machine for dumping kernel core becouse it's
production server it should be up and running. But I'll try same at home.
It seems that kernel mbuf are exhausted by the route cache or the
arpresolver becouse I can see a lot of unresolved arp requests in the
routing table.
