C2960S switches reset SFP+ ports hourly

[Baker Risk]

We have several C2960S switches that seem to reset their uplink SFP+ ports at the same time each hour. It looks like it's only a brief reset but any Cisco phones we have attached to these switches will lose their connectivity to our Subscriber and reset. Has anyone else seen this? We are running iOS 15.2(2a)E1 due to a different error we were having (%ENTROPY errors), and Cisco TAC recommended we upgrade to the latest code. I included a "sho log" to demonstrate what I'm talking about. The interface in question is Gi1/0/49 which has a GLC-T in it that uplinks to our Data Center switches.

I see you have 2960s, but there is know bug for the 2960-X series regarding GLC-T and other SFPs.

So, this maybe effecting your switch as well but not sure.
