these message are seen may be because for following reason, the adjacency table might not have updated with the updated ARP entry when the CEF trying to locate valid adjacency for destination prefix/ip address. This might seems to be the timing issue, which is temporary.
if this continues check for the hsrp/glbp interfaces.
thanks for your reply, but there is no hsrp configured, just an interface vlan. with 2 static routes and the problem was there for more than an hour before we decided to rollback.
Is there a BugId with this problem in Cisco DataBase.
here is a show ip route
