Keep alive timeout on multiple bot sessions

[ghost]

So I decide to develop a bots for my PvP CTF-minigame, and everything was ok before I've start to connect multiple bot at once. I know about connection threshold and stuff, but c'mon, I don't really have some HEAVY stuff like radars which monitoring every damn thing in real time. My CPU is used for less than 10% and I start bots from the same machine where the server is running.

When the first bot connects, everything is okay. But when second, the first bot start be laggy (ping check says that bot ping is 4k+ but bot connecting from localhost, so it's just impossible to have ping problems) and after a little period of time will be kicked from the server due to keepAliveError. I really can't understand and even imagine why this is happening.

Here is a script: bot.txt

ps. I'm not a native eng speaker, so sorry for any grammar mistakes, I tried to write this text without google translator lol.
