[exim] Exiscan/spamd problem : "error reading from spamd soc…

I cannot run spam checks any longer because of errors reading to an from
the spamd socket. This may be a DNS problem but I don't know enough
about DNS to makes sense of a tcpdump; the queries seem to flow in both
directions fast enough. I have disabled RBL checks in SpamAssassin as a
precaution, but the problem continues, with many spamd connections to
localhost locked in a CLOSE_WAIT situation.

Any help much appreciated
