Hi,
I have an ASA5585-SSP-20 where I see a lot of overruns on the Internal-Data0/1 interface.
This is an active/standby setup.
None of the physical interfaces experience overruns, and the CPU, memory and other stuffs seems fine.
Interface Internal-Data0/0 "", is up, line protocol is up
Hardware is i82599_xaui rev02, BW 10000 Mbps, DLY 10 usec
(Full-duplex), (10000 Mbps)
Input flow control is on, output flow control is off
