trouble with whiteclnt

Hi --

I recently had to rebuild my mail system after a disk failure, and am
having a weird problem with DCC.

The symptom is that after a while of operating correctly, it begins
ignoring the global whiteclnt file and so messages that should be accepted
are not. Also, and oddly, the whiteclnt.dccw file winds up with a bogus
date of 12/31/1969.

Here is an example of a message that should have been accepted but wasn't:

  Jun  2 02:07:41 is1 sendmail[84418]: j5277dZL084418: Milter: data,
  reject=550 5.7.1 Bulk mail rejected: please see
  <http://www.gstype.com/email.html>.

  Jun  2 02:15:13 is1 sendmail[84448]: j527FC7T0844418
  from=<daily_headlines@ms3.lga2.nytimes.com>, size=57926, class=0,
  nrcpts=1, msgid=<200506020715.j527FC7T084448@is1.gstype.com>,
  bodytype=8BITMIME, proto=ESMTP, daemon=MTA,
  relay=content119a.lga2.nytimes.com [199.239.138.162]
  
It should have been accepted because 199.239.138.0/24 is in the whiteclnt
file:

  $ grep 199.239.138 /var/dcc/whiteclnt                                                                                                                    
  ok      ip      199.239.138.0/24  

The last oddity that I notice is that there are two dccm processes
running, and I don't recall that it used to be that way (although that may
be just me misremembering).

  $ sudo /var/dcc/libexec/rcDCC stop
  $ ps -ax | grep [d]ccm             
  $ sudo /var/dcc/libexec/rcDCC start
  $ ps -ax | grep [d]ccm              
  97645  ??  Ss     0:00.00 /var/dcc/libexec/dccm -U userdirs -SHELO...
  97647  ??  S      0:00.01 /var/dcc/libexec/dccm -U userdirs -SHELO...
  
I am using the most recent version of DCC on FreeBSD 4.8-RELEASE with
sendmail 8.12.11. I only use dccm, not dccd, dccifd, etc. Any light that
anyone can shed on this would be much appreciated.

Thanks.
