Error message "Failed to locate egress interface"

I can see this message logged in every two minutes, "%ASA-6-110002: Failed to locate egress interface for UDP". It looks like for some reason the ASA looses the dynamic route to the Internet.The gateway interface on the ASA for the phone subnet is 192.168.150.1 and 192.168.148.2 on the inside interface on the ASA. I do not understand what can be the problem.Is there anything missing ?

ASA gives this error message when VPN Client tries to use peer-to-peer program and that traffic goes into the tunnel, where the peer-to-peer server does not reside. Configure the split tunnel in order to resolve this issue so that the traffic that needs to go out to the internet does not travel through the Tunnel and the packet is not dropped by the firewall.

While searching the cause for this on cisco.com, i got an explanation for this saying:-

An error occurred when the security appliance tried to find the
interface through which to send the packet.

• protocol-The protocol of the packet
• src interface-The interface from which the packet was received
• src IP-The source IP address of the packet
• src port-The source port number
• dest IP-The destination IP address of the packet
• dest port-The destination port number

Recommended Action Copy the error message, the configuration, and any
details about the events leading up to the error, and contact Cisco TAC.

So i guess that ASA is probably not properly set up to handle IPv6. try to set it up properly and also do a reboot of the Router. Hope this will fix the problem. Do let me know the result.

Thanks for the quick response mate. I think you are right. Let me try to set the ASA properly and reboot the router. I'll get back to you with the results. Hope this works for me. Anyways, thanks a lot for the help.
