portsentry and courier: RPC error

[Vadim <vadim@kutsyy.com>]

I am running portsentry and courier, and I am getting this error in my 
syslog:

imapd-ssl: pmap_getmaps rpc problem: RPC: Unable to receive; errno = Connection reset by peer

If I stop either of the services, error stops. There is no mentioning of port 530 (courier rpc) in portsetry.conf.  How do I fix RPC?  Do I need to worry about it?

Thanks,
