Intermittent application drops - possible network issue

Seeing intermittent drops between some application server and a database server.  Issue may not be network related

However, the rule out I am checking the network elements

Both the application servers vlan and DB vlan hvae the ASA FW as their default gateway.

The ASA  has 2 physical interfaces (gig) setup with multiple sub interfaces

On the switch side all the vlans are trunked up to the ASA.

If I check the ASA interfaces I see the following

        88832067422 packets input, 82271119214695 bytes, 0 no buffer
        Received 3880059 broadcasts, 0 runts, 0 giants
        5148799 input errors, 0 CRC, 0 frame, 5148799 overrun, 0 ignored, 0 abort
        0 pause input, 0 resume input
        0 L2 decode drops
        41170738277 packets output, 27353471299484 bytes, 312908 underruns
        0 pause output, 0 resume output
        0 output errors, 0 collisions, 0 interface resets
        0 late collisions, 0 deferred
        0 input reset drops, 0 output reset drops

There are a small number of input errors / overruns (0.0058%).  Is this within acceptable levels ?

The corresponding switch port channel is showing TX discards

  4 interface resets
  30 seconds input rate 71021368 bits/sec, 18165 packets/sec

Any advice on potential issues here ?

Many thanks

On the ASA - is this the only interface you are seeing the overruns on?

Same question on switch - is this interface that you are seeing output drops?

Clear the interface counters and watch the counters.

Based on the output that you are showing above, traffic may be bursting, killing the buffers on the interfaces.
