First set bayes_auto_expire 0 This a good idea anyway as auto-expiry can cause problems during scanning. Running sa-learn --force-expire from cron is better. I would also delete the existing database in case there is some corruption. It's worrying that the nspam count drops to zero. It wouldn't hurt to run smartctl -t long on the drive device followed by a full fsck. Also check your logs for warnings.
