Title says it all, had a server require a re-boot yesterday; now every 10seconds to 2minutes I receive line after line after line of

su: (to oracle) root on none

I've asked my DBA who is running Oracle Cloud Control on this server to check his settings, he notes there is no clustering and this server does not have SLES HA extensions (which google-fu leads one to believe is the culprit). The Oracle forums are of no use as they point the DBA's back to the SYS Admin and say it's my fault.

I've never seen this, anyone have a clue what this may be?
