Buffer Overflow kick

Hello,

on my server 194.26.183.47:27015 up to 50 people are playing on it and if too many people are talking at the same time, someone randomly flies off the server with the error message "Buffer Overflow". For example: One comes on the server and says hello the other 20 say hello back then someone flies randomly (buffer overflow)

I have noticed that the In value in the net_graph goes up to 6000 when more than 10 are talking at the same time.

I really hope they have a solution for me, I've been running the server for 15 years.

Thank you very much

Best regards Dellmuth

The only time I have seen this kind of issue is with players using malicious packets to intentionally drop all players on the server via voip buffer overflow.

It likely occurs on the client end, but you might be able to fix it from the server side settings.

What audio codec, tickrate, maxrate, and net_splitpacket_maxrate does the server use?
Do you have compression enabled ? if so, what net_compresspackets_minsize ?
