This machine of mine has lots of network load (it's a gateway, runs
9 PPP lines etc).

P120, 32 MB RAM, 3c509 Ethernet, 9 PPP links over serial lines.

No reason to panic, then.  I just thought I had seem some talk about a mbuf
leak on one of the NetBSD lists a long time ago..

Odd.  A news server which has received over 2 GB since last reboot (ie.
the byte count is negative in netstat -p tcp) reports only 16 mbufs in
use - still there are 246 KBytes allocated to network.  Why does it
allocate so much if it only needs a few K's?  Doesn't it ever release
the mbufs to the kernel pool?
