Uplink set - SNMP - "Interface Speed Changed"

I have multiple C7000 VC's that are reporting speed changes on my uplinks (via SNMPs, but I don't see any errors logged that would indicate one of the links is dropping.. how can I diagnose this?

 

Sample:

 

2015-06-29 13:39:21 lag24 Interface changed: [ifSpeed] 40000000000 -> 30000000000; [ifHighSpeed] 40000 -> 30000
2015-06-29 13:34:23 lag24 Interface changed: [ifSpeed] 10000000000 -> 40000000000; [ifHighSpeed] 10000 -> 40000
2015-06-29 13:29:25 lag24 Interface changed: [ifSpeed] 40000000000 -> 10000000000; [ifHighSpeed] 40000 -> 10000
2015-06-29 13:04:25 lag24 Interface changed: [ifSpeed] 10000000000 -> 40000000000; [ifHighSpeed] 10000 -> 40000
2015-06-29 12:59:33 lag24 Interface changed: [ifSpeed] 40000000000 -> 10000000000; [ifHighSpeed] 40000 -> 10000
