Problems with 5.0_RC2

Hi,

I'm having weird problems with NetBSD/amd64 5.0_RC2 (inside VMware ESXi), after 
upgrading from 5.0_RC1 to 5.0_RC2 my mail server is no longer able to deliver 
mail. The trouble makes is dspam, it simply dies without anything in the logs. 
I've even rebuilt clamav and dspam after upgrade but it didn't help anything.

Build dates:
------------
RC1: 2009-01-28
RC2: 2009-02-18

Here's how I noticed something was wrong:

# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
xxxxxxxxxx    13558 Thu Feb 19 11:05:09  xxx@xxx
               (connect to xxx.xxx[/tmp/dspam.sock]: Connection refused)
                                   xxx@xxx
# ps axw | grep dspam
#
# /etc/rc.d/dspam restart
dspam not running? (check /var/run/dspam/dspam.pid).
Starting dspam.
# ps axw | grep dspam
 2715 ttyp1  S    0:00.00 /usr/pkg/bin/dspam --daemon
# postfix reload
# postfix flush
# ps axw | grep dspam
#

I downgraded back to 5.0_RC1 and it's stable again, i.e. mail gets delivered 
correctly.

# for i in base.tgz comp.tgz kern-GENERIC.tgz man.tgz misc.tgz text.tgz
do
  echo $i
  tar xpzf $i -C /
done
# reboot

# postfix flush
# ps axw | grep dspam
 199 ttyE0- Sl   0:01.80 /usr/pkg/bin/dspam --daemon
# mailq
Mail queue is empty
#

Any ideas what's going on here? Could this be some kind of library issue?

I'll test now with RC2 kernel and RC1 userland to see if that works or not...
