help with logcheck

Hello,

I had logcheck for long time on my machine, but last weekend managed to
run the job every hour from root cron. The problem is that whenever the
logcheck runs, it mails me a following message

Unusual System Events
=-=-=-=-=-=-=-=-=-=-=
97026
831


Though the first number (97026) doesn't change, second changes. What is
the problem? I am running RedHat 7.1 on my box running and I also
updated it with all patches through rhn_check last weekend.

Is there a problem with my system?
