CSCvt63484 - ASA High CPU with igb_saleen_io_sfp_mod_poll_thre process

[ShafeeAhmad4583]

Would this bug trigger If I run 9.12.2.9 on Platform 5545-x ad 5585-x ?

In my opinion this is a problem connected with ios upgrade to ver 9.12.(4) and SFP module ASA-IC-6GE-SFP-A. Once I removed this extending card the processor usage fall back under 10%.

In case the module is inserted the processor usage exceeds 30%

Same problem occured on 5515-X

Do you guys experience any degradation in performance (e.g. drops, errors, etc) or is it just higher cpu usage? 

[dvorakm01]

Latency too high, based on ping statistics from a local machine to ASA is about 12% of packets lost.

A process with high processor usage has been found through CPU usage command --- igb_saleen_io_sfp_mod_poll_thread

Problem occured after I upgraded to IOS 9.12(3) on May 17th 2020

ASA has been upgraded to latest IOS ver 9.12(4) on June 24th 2020 but problem persisted

Ping statistics for XXX.XXX.XXX.XXX:

    Packets: Sent = 95, Received = 83, Lost = 12 (12% loss),

Approximate round trip times in milli-seconds:

    Minimum = 6ms, Maximum = 568ms, Average = 77ms
