I know this is old, but typically when you see something like this it's because a deadlock occurred and the app that triggered the deadlock has long since moved on -- the victim of the deadlock got warned and either failed, or logged an error or retried, and either way has moved on to other productive things.

If you're just using the software (e.g. Wordpress if you don't work at Wordpress), you could report the deadlock as a possible bug.
