It appears to unintentionally be doing something different with traffic based on the source address, not the destination address. I realize this can be done intentionally - but that is not the case here (unless somebody isn't telling me something).I don't think we can determine that it has anything to do with source address based on data shown. 38.104.148.5 could very well be 6500 and somehow broken adjacency to 74.125.226.6, perhaps hardware adjacency having MTU of 0B, causing punt which is rate-limited by different policer than TTL exceeded policer.
