Cisco Mobility Express (AIR-AP1815I-I-K9) Wi-Fi Hangups with Error Log

[ALI12]

Hi everyone,

We’re experiencing intermittent hangups with our Cisco Mobility Express setup on model AIR-AP1815I-I-K9 running software version 8.4.100.0.

After reviewing the logs, I noticed several errors around the same time as the Wi-Fi hangups.

Could anyone shed light on whether these errors indicate an underlying issue or if they are expected logs under certain conditions? Any guidance or troubleshooting tips would be greatly appreciated.

Thank you!

                                      - FYI : https://bst.cloudapps.cisco.com/bugsearch/bug/CSCui51972
            It mentions an older version but in all circumstances mobility express AP should use the last/latest version
            as pointed out in :
