"Buffer overflow in net message" Fix?

So I tried joining some Serious RP servers today, and I keep getting this error, can anyone help?

It’s basically the Source engine saying “The server you’re joining is laggy as fuck and doesn’t have half a braincell left to let you join.”
This is not uncommon for GMod servers since they’re known to use alot of bandwidth, just keep trying to join.

Fixed, thank you very much.

I’m not entirely sure as to how you applied that fix, but sometimes, setting “myinfo_bytes” to a retardedly high number seems to work when joining servers with too much shit going on.
