Occasional spamassassin: Connection refused

Hi There,

We are using debian sarge postfix>amavis(sa+clamav)>dspam and getting the occasional:

warning: connect to transport spamassassin: Connection refused

In our postfix mail log. Any idea where to being here? Is there some sort of limit that needs to be raised?

Currently processing around 90-100 msg per min on a dual xeon 2.8 running 2.6.8-13-em64t-p4-smp with 2GB of RAM.
