[expert] Cron error

[Expert User]

Ever since I have installed LM 7.2 I'm getting this mail to root
with subject: Cron <root@localhost> run-parts /etc/cron.daily
(sent by cron Daemon)

---------------------- Contents of mail -----------------------------
DB2 problem...: missing or empty key value specified
Reading active file failed, exiting (see syslog for more information).
Has fetchnews been run?
---------------------------------------------------------------------

What is the problem.

I'm running LM 7.2+ in High security setting.
