Hello all,
I have a Soekris net5501 acting as a router and proxy for certain VLANs.
X number of days after boot, I was experiencing network lockups (serial
console still worked fine). I think I have tracked the issue down to
mbuf exhaustion. I increased kern.maxclusters as a temporary fix, but
it appears that I will still need to reboot in the near future.
"netstat -m" produces:
43827 mbufs in use:

I run a Tor transparent proxy on an open SSID/VLAN on this box. I
suspect this is the culprit, but is there any way to confirm other than
killing the server and waiting to see if the mbufs rise?
