Basicly when I run my bot I get this:

C:\Users\Name\node_modules\agario-client\agario-client.js:415
// If you need that server support, you may create issue https://github.com/pulviscriptor/agario-client/issues

Usually this kind on crash happens when agar.io changes protocol.
I run examples/basic.js for 20 minutes and can't reproduce crash.
How often you see that crash?
Does it happens in examples?
Did you updated your agario-client? (last protocol-change-fix that caused "random" crashes was Nov 29, 2015)

[pulviscriptor]

Running examples/multiple.js for 3+ hours with 5 clients connected, still no crashes.
If somebody else have crashes please report them here.

@pulviscriptor It may be that I'm running 50+ bots

[pulviscriptor]

DrTheGoat, how often you see crashes?

[ghost]

@pulviscriptor Within minutes of running

[pulviscriptor]

@DRTHEGOAT Can you set debug to 5 and show me last 5 packets before crash?

[pulviscriptor]

@DRTHEGOAT You can run script like node bot.js > debug.log and then look in debug.log

[ghost]

@pulviscriptor Thanks

[DaAwesomeRazor]

I get that every day it crashes all the time

[DaAwesomeRazor]

It happens when i run like 60 bots for a long time(I made bots too)

[pulviscriptor]

@DaAwesomeRazor Please set client.debug = 5; and show me last 5 packets so i can see packet that causes crash.
Output will be huge so run script like node bot.js > debug.log and then get last lines from debug.log

@DRTHEGOAT Thank you very much! This is exact packet that i need!
After investigating i see strange thing here.
This is packet ID 49 and here is processor from original code http://pastebin.com/raw/LbfZAPw3
So i made port of it http://pastebin.com/raw/VX2buBmD
It is crashing and this is what i see https://i.imgur.com/94E8s3s.png
But if i move offset one byte forward before leaders = []; i will get this https://i.imgur.com/lQcdIbl.png
Sooooo...

@DRTHEGOAT @DaAwesomeRazor somehow your packets got one byte more/less of data. I don't know how that is possible.
I assume you use SOCKS servers so lets think its SOCKS servers breaking packets somehow.
I think i will add something like event for packet errors so you can handle them from your code.
I will try to do it today.

[pulviscriptor]

@DRTHEGOAT @DaAwesomeRazor
Event client.on.packetError(packet, err, preventCrash) added. Check readme.
Example of usage:

bot.on('packetError', function(packet, err, preventCrash) {
   bot.log('Packet error detected for packet: ' + packet.toString());
   bot.log('Crash will be prevented, bot will be disconnected');
   preventCrash();
   bot.disconnect();
});

*My fix is not best solution, but i don't know what else i can do with bytes changes.

[issy123]

You probably edited agario-client.js in the node modules?
or you named the argument variable name wrong for example:

bot.on('packetError', function(packet, err, preventCrash) {
   bot.log('Packet error detected for packet: ' + packet.toString());
   bot.log('Crash will be prevented, bot will be disconnected');
   preventCahs();
   bot.disconnect();
});

What also could be possible is that you got the number of arguments wrong

bot.on('packetError', function(packet, preventCrash) {
   bot.log('Packet error detected for packet: ' + packet.toString());
   bot.log('Crash will be prevented, bot will be disconnected');
   preventCrash();
   bot.disconnect();
});

But it should be this:

bot.on('packetError', function(packet, err, preventCrash) {
   bot.log('Packet error detected for packet: ' + packet.toString());
   bot.log('Crash will be prevented, bot will be disconnected');
   preventCrash();
   bot.disconnect();
});
