[Observium] All ports at each polling showing "interface changed:" event log

We are at 7608.

During each polling run, every port on our system shows an interface changed event log: https://s3.amazonaws.com/uploads.hipchat.com/131939/956300/RLSqGEGgF09oIZS/u...

Here is the port poller from one device showing this issue: https://s3.amazonaws.com/uploads.hipchat.com/131939/956300/4ADJVr2DdsmjgXT/l...

This error stands out: SQL[UPDATE `ports` set `port_label_base` ='Null',`port_label_num` ='0',`ifLastChange` ='2015-05-19 05:42:34' WHERE `port_id` = '3872'] SQL RUNTIME[0.00006795s] ERROR[Error in query: (Unknown column 'port_label_base' in 'field list') 1054] PORT updated rows=

Looks like I'm missing some structure from my DB. Please let me know what is needed to sort this out.

Thanks,

Matt
