I am getting a very high number of temporary rejects in my sendmail log file with 'DCC failure'.

Jul 23 12:18:33 mucs025321 sm-mta[1040]: i6NAICTI001040: Milter: data, reject=45
1 4.7.1 DCC failure

I am using DCC 1.2.50, greylisting is enabled.  
 From reading the man pages I would guess this happens when dccm is not able to contact a dccd server.  

'cdcc info' shows very reasonable values.  So I don't think that contacting a dccd server is the issue.  I have two other mail gateways on the same subnet still running dcc 1.2.39. These two servers do not have any issues.

Any idea why this is happening?
