Error message decode Help Needed

I get the error message following two devices on my network:

CRYPTO-4-RECVD_PKT_MAC_ERR: decrypt: mac check failed for the login id = local = remote spi F1E30F16 seqno = D 0000905 = =

Cisco decodes the message as:

% CRYPTO-4-RECVD_PKT_MAC_ERR: decrypt: mac check failed for the login id = [dec]

Explanation MAC check treatment has failed. This may be due to the use of the wrong key to the other party during calculations of MAC. Some might consider cela a hostile demonstration.

Contact fast action recommended that the administrator of the peer.

Can someone help me understand this?

I searched in vain for MAC check treatment, I also checked for calculations of MAC etc...

I need to know what causes this error, and it's a significant problem. The VPN seems to work, but I lose as a result of this performance?

Thank you

Gareth

If you have verified that your keys are correct, it seems that this could be a bug.
