%CRYPTO-4-RECVD_PKT_MAC_ERR: decrypt: mac verify failed for connection id

Iam getting this errror continously. When i get rhough cisco output interpretor i see this is due to wrong key mapping with peer.But i verified everyting is correct.Suspect it could be a bug.Could anybody explain me why is this error occuring more deeplly.What is the solution?

If the configs are OK, then most probably its a bug.

Try disabling fast switching/cef, then clear the cache (clear ip adjacency and clear ip cef prefix-st....) and then try. Do this on both sides.

Have done that ,but no change.Still the erro poppin gout. I have even reloaded the router to see it makes any diff,but of no use.

If it is a bug ,could you specify me the bug id. Can we try upgrading teh iOS.

Pls see the output from the router in the attachement .I see there is some packet drops due to esp_auth Fail .
