Alrighty, so I got super bored since I noticed the frequency in crashes varied quite severely after a period of downtime.

You shouldn't be setting kac_rcon_crashprevent to 1 in the code. It needs to be set in server.cfg.

*shrugs* I'm using my own build of KAC so I figured I might as well just set the values in the .sp file. The only thing I had left untouched was rcon.sp besides that one value which should have enabled it.

I guess the only protection against this is to firewall off your 27015 TCP port.

No, the issue is that changing the default values does not change KAC's internal value. Plus it doesn't trigger the code to make the patch.

Either way, the main issues which caused things not to work for you was because you modified KAC.

Few hundred of invalid rcon attempt in a few seconds but server stayed alive.

Like I said, the issue was that he improperly modified KAC. Its not a bug with KAC.
