Have there been any effective resolutions to events generated in this Bug? Is this impacting production for anybody?

Thanks for your response,

Hi all,

I faced that issue on a 9800-L-F with version 17.3.6. Does anybody has some news about it? Does it impact the network? Or can it be ignored?

Upgrade needed? Some news from Cisco?

Thx

I too observed the same messages on the equipment I admin for a period of time; then it ceased (1/21/2023 - 2/4/2023).  I admin a 9800-80 in HA running 17.3.6 code. Found this link on the same subject: https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs71716. The version I'm running is not mentioned but since it says that no workaround has been found, I'm assuming my code inherited it. Cisco seems to be gathering info on it and on that link there's information they're asking for to reach RCA.

@S. K. - are those logs repeating constantly in your environment? I'm not seeing them repeat so I might not open a ticket but if you share the same behavior as me, I might.

Hi,
Somebody else had this error on WLC 9800?
Does it impact the network?

Thank you!
