Fedora includes incron (cc'ing incron package maintainer), which puts its logs in /var/log/cron. That makes the logwatch report be full of unmatched entries from incrond, which isn't pretty. We should do something about that.
Hello, please could you attach your /var/log/cron file here?
Created attachment 158612 [details] cron log Sure. To shorten, I've grepped it for just the incrond messages. This should be a pretty useful sample, as I was testing and there's a bunch of both normal and error messages.
Thanks fixed in logwatch-7.3.6-4.fc8.
