Here is a bizzare situation that I have - I upgraded from SpamAssassin 2.60 to 2.63 and I started to receive all these errors. I am still able to have SpamAssassin parse my emails correctly but I am wondering about these errors.
Feb 17 23:49:05 elmo spamd[17932]: debug: Failed to parse line in SpamAssassin configuration, skipping: spamphrase_highest_score 38220
Um.. looks like you picked up some ancient config files along the way.. the spamphrase feature disappeared in 2.50.
Look around in /usr/share/spamassassin for 40_spam_phrases.cf... you shouldn't have one anywhere in sight.
Also make sure the rest of your default .cf files are the same as provided in 2.63 and not some older version.
