This is actually a real issue for new players in the server. New players are missing audio files for the zombies causing this spam in the console, especially in defend situations where everyone is spamming the zombies. In maps where there is no zombie defense spamming you might avoid this entirely. In other maps with lots of defense, you will crash 100%. You can notice RAM usage increase sharply for few seconds before this (Like almost a gig per second).
And no, players cannot fix this. I've tried removing all downloaded assets and download them again. Same for sound.cache files. Also tried verify integrity. Problem is in the server not sending those audio files to the client in the first place. Or, the files are possibly corrupt on the server? So old players who have working files can play normally, while new players can't.
Ples fix if you want any new players to be able to play on your server. Or give us a zip package to download all used assets.
