: %SYS-2-CHUNKBOUNDSIB: Error noticed in the sibling of the chunk

Dear friends,

I've received the following error after configuring an inbound access-list on a cisco 7200 router.

The access list was implemneted for blocking a certain udp attack from a customer towards our router. (Approximately 25Mbps)

The weired issue is that the error was logged on the router only 2.5 hours after the access list implemenation,

although packet loss between the router to local devices &   internet already occured approximately 30 minutes after implemenation.

As soon as the access-list was removed the issue has been resolved and packet loss stopped.

I'll be glad if someone can shed some light on this error/Bug, and provide solution for it (perhaps IOS upgrade?)

Thank you!

Access list:

deny udp X.X.X.X  X.X.X.X eq [protocol name] any log

deny udp X.X.X.X  X.X.X.X eq [protocol name] any log
