PIX 501 6.3.3 - Received Invalid Cookie notify

[gmcmanus93]

I have VPN connection that wont stay connected. Concerntrator 3005 log indicates:

11127 08/05/2004 09:47:07.750 SEV=5 IKE/1 RPT=2116 55.55.55.55 Received Invalid Cookie notify - retrying last packet

Any idea what may be causing this? The connection type for the pix is cable with a static IP. Config is the same as other sites.

Have any one come across this error before. I am looking for suggestions or ideas of what might be causing this problem.

Thanks.

I am getting the same error on a 3015 concentrator. Did you ever find out the issue with the 3005?

I upgraded the concentrator from 3.5 to 4.1.4. After upgrading, I did not see this error any longer. I found some documentation that recommended the first step to troubleshooting this was to upgrade the IOS. What version are you at?

My vpn is between two 3015's both running 4.0.1C

I get the cookie msg only on one 3015.
