ASA-1-105005: (Primary) Lost Failover communications with mate on interface INSIDE

Yesterday I was repeatly seeing this kind of message on my ASA 5525. You can see the sequence happens within a second. Now suddenly these errors have stopped. v9.4.12.7. Any idea what might cause these?

Most case layer 2 Issue, check some Physical how this INSIDE Interface established connectivity with other swithes ?

Do you see Fail over when this mesage occur. not remember the bug, i see some bug around this (if the device not Failover due to this interface down and up, then its bug,
