This should probably be the default anyway. All of my systems (stable/10) have custom logging where each facility has its own file. Also *.*;mark.* is sent to /dev/ttyvb and to the central log host. /dev/ttyvb was pretty busy on the log host. Making devd less chatty does have its merits. The next servers I buy will probably exclude a DVD player.

Killing bsnmpd stops the cpu usage but does not free up memory. Both affected systems are amd64, one having moved from r297555 to r298723, the other from r297555 to r298722. Another amd64 system that went from r297555 to r298722 appears to be not affected. The two affected systems are on an internal LAN segment and there is currently no application connecting to snmp on those machines. What would be useful debugging data to collect in this case?
