I'm not sure either, it would require two concurrent requests to be processed, but AFAICS oidentd only uses a single netlink socket. Perhaps multiple running instances or something else using the inet_diag interface? You might be able to trigger it without this patch by running "while true; do ss -tn; done" while doing ident queries, but just running the while loop a couple of times in parallel doesn't seem to trigger it here.
