HELP w/portsentry - blocks ip in ignore file

I've been using portsentry for a while now.  It's great love it.
However, recently it insists on blocking an address in the ignore file:


# grep '209.172.84.149' /etc/hosts* /usr/pkg/etc/portsentry*
/etc/hosts.deny:# DenyHosts: Wed Nov 17 07:38:10 2010 | ALL: 209.172.84.149
/etc/hosts.deny:ALL: 209.172.84.149
/etc/hosts.deny.purge.bak:# DenyHosts: Wed Nov 17 07:38:10 2010 | ALL: 
209.172.84.149
/etc/hosts.deny.purge.bak:ALL: 209.172.84.149
/usr/pkg/etc/portsentry.ignore:209.172.84.149/32

No matter how many times I remove it from the files and restart portsentry, it 
insists on blocking the ip address within a few seconds.

It ignores other ip addresses in the ignore file.

Clues as to where I'm going wrong are appreciated.

TIA,
Paul
