Odd error

I just put a new kernel on a server and all of a sudden I'm see'ing this:

sending pkt_too_big (len[1500] pmtu[1442]) to self sending pkt_too_big (len[1500] pmtu[1442]) to self sending pkt_too_big (len[1500] pmtu[1442]) to self sending pkt_too_big (len[1500] pmtu[1442]) to self

A LOT in my dmesg. I think it's most likely an app which is doing something stupid but I'd like confirmation before I go smack someone.

:wq!
