[Observium] up null up, anyone similar?

Anyone else have anything similar to this:

Date Device Entity Message 04/30/13 10:55 PM bravo eth1 ifOperStatus: -> up 04/30/13 10:55 PM bravo eth1 ifAdminStatus: -> up 04/30/13 10:55 PM bravo eth0 ifOperStatus: -> up 04/30/13 10:55 PM bravo lo ifOperStatus: -> up 04/30/13 10:50 PM bravo eth1 ifOperStatus: up -> NULL 04/30/13 10:50 PM bravo eth1 ifAdminStatus: up -> NULL 04/30/13 10:50 PM bravo eth0 ifOperStatus: up -> NULL 04/30/13 10:50 PM bravo lo ifOperStatus: up -> NULL

over and over in the event log? Weird part is, we have another server in here (this is the Linux, and one Windows for now) and it only happens to the Linux one.
