This post is somewhat similar but mine is rather specific.
CRON: pam_unix(cron:session): session opened for user root by (uid=0)
Is this really a bug? In our system this process is creating entries in every 5 minutes making the log backup guys' life very hard. Lots & lots of entries are being stored on the disk.
As per the following links, do we need to fix this issue or can we at least increase the time of listing between the entries?
Can I at least reduce the time between entries? For my server currently it's 1 pair of entry in every 5 minutes. Say, I've increased the time to 30 minutes, would I miss any login attempt (legit and hacking both)?
