I am using NetBSD 4.0_RC3. My server acts as firewall and router. A 
nameserver is running, but no other services. The value for NMBCUSTERS is 

The problem is that the value for mbufs in use is increasing by more 
than 1500 per day. After some days the kernel reports INCREASE NMBCLUSTERS 
and no more network communication is possible. A reboot is necessary.

At the moment netstat -m shows:

9670 mbufs in use:
         8975 mbufs allocated to data
         663 mbufs allocated to packet headers
         32 mbufs allocated to socket names and addresses
2 calls to protocol drain routines

Any idea what the problem could be?

Thank you for your efforts
