That does sound a little odd.
I don't think that is is to do with ipvsadm, as I think that the
strings come from the kernel. Can you see if the same problem shows
up when you cat /proc/net/ip_vs_conn ?
Once these connections get into that state, do they stay in that state
until they timeout, or do they progress to a different state?
Could you send some examples of this behaviour?
I suspect that it is harmless, but I also think it is
a bug in the the reporting functionality.
