We found the problem. The machine we're using is an LDAP client for all ~8000 users, and it seems that spamc/spamd is failing if the username is not cached in nscd - simply typing "ls -l /home" solves it temporarily until the cache timeout, since all objects are then cached. We fixed this by running that command via a cron script every 15 minutes. So would this be a bug in spamassassin?
