This isn't Valve's problem, it's the server's problem (no offense intended).
I've proven with 100% certainty that the console errors are a result of player death. There are no errors until the instant someone gets killed, then my console is blasted with them. The last line before each console error 'blast' is always a player's death by another player though so I feel confident this error is being caused by either the floating bodies or the gore mod.
