Cisco to Sonicwall VPN - payload processing error 500 points to winner

We have a Sonicwall 4060 enhanced. A customer of ours is useing a CISCO firewall and we have setup a SITE to SITE VPN tunnel. The tunnel comes up and thier users are able to access our resources via telnet but then randomly they drop connectivity. I was looking through the logs on the VPN IKE and found that the following error messages showed up.

156 06/19/2006 05:50:07.080 Info VPN IKE Received IKE SA delete request, 500, 500  
158 06/19/2006 05:50:07.080 Info VPN IKE Received IPSEC SA delete request, 500, 500 SPI:0x4441afce      
160 06/19/2006 05:50:03.080 Error VPN IKE NOTIFY: -payload processing error, 500, 500    

When this happens I think is when people are getting randomly dropped. Any idea what these errors are caused from?

There is a ISAKMP keepalive setting that is disabled on older versions of PIX.
Need to match the Sonicwall keepalive with the PIX

It was the keep alive. We just turned it off all together. Thanks for the help.
