Hello,

i have 2 problems with snmptrapd (net-snmp 5.4.2.1 amd64) on FreeBSD 7.1 
release.

1.  snmptrapd forks very slow.

root$ time /usr/local/etc/rc.d/snmptrapd start

2. no traps.

root$ cat /etc/rc.conf.d/snmptrapd
snmptrapd_enable="YES"
snmptrapd_flags="-a -p /var/run/snmptrapd.pid"

root$ cat /usr/local/etc/snmp/snmptrapd.conf
authCommunity log XXXXXXXXX
logOption f /var/log/snmptrapd.log


tcpdump shows traps in interface but nothing in logs.


ktrace shows:

   316 snmptrapd CALL  close(0xc)

I tested these config files on i386 and it works fine. Seems it 
something with amd64.

Any ideas?
