bind timeouts

Hi,

for some times, I have some troubles to send e-mails, they
are returned w/ a host unknown error message (the relay)...
I spent a whole day to track down the problem w/o success.

however, it seems to be located around bind, but I don't know
if it's the client side or the server side which is broken,
maybe the TCP stack !

I'm running -current last updated around 18 April 2004.

# uname -a
FreeBSD gits 5.2-CURRENT FreeBSD 5.2-CURRENT #26: Tue Apr 27 03:51:12 CEST 2004
# nslookup -q=txt -class=CHAOS version.bind. 0
Server:  localhost
Address:  127.0.0.1
VERSION.BIND    text = "8.3.7-REL"

here are some outputs of the host command :

# time host smarthost
smarthost.gits.fr.invalid has address 62.62.156.27
smarthost.gits.fr.invalid has address 62.62.156.28
    0.05s real     0.00s user     0.04s system
# time host smarthost
smarthost.gits.fr.invalid has address 62.62.156.28
smarthost.gits.fr.invalid has address 62.62.156.27
    5.08s real     0.00s user     0.03s system
# time host smarthost
    5.08s real     0.00s user     0.04s system
# time host smarthost
    8.14s real     0.00s user     0.04s system

so, sometimes, I got a rapid answer, sometimes a slow answer
and sometimes no answer !

here are some other outputs regarding localhost :

# time host localhost
localhost.gits.fr.invalid has address 127.0.0.1
    0.06s real     0.00s user     0.03s system
# time host localhost
localhost.gits.fr.invalid has address 127.0.0.1
    5.19s real     0.01s user     0.03s system
# time host localhost
localhost.gits.fr.invalid has address 127.0.0.1
   10.14s real     0.01s user     0.01s system
# time host localhost
Host not found.
   30.38s real     0.00s user     0.04s system

any hints ?
