Message is larger than maximum allowed size

[newElectrotanker]

Hi All!

I see much errors when I start electrotank server:
"Message is larger than maximum allowed size (1411397166 > 1048576)"

Please, help me fix it

Are you sending really large messages? Let me know if that is the case, because there are other things to be done. The most likely problem is one of these:

A client crashed and when it did so sent a garbage message to the server. Either ignore or try to figure out why your clients are crashing.
A user is trying to hit an ES5 port with the wrong protocol. For example, an AS2 client has to use text protocol, and if it is hitting your BinaryTCP port or HTTP port, you would see something like this.
Some non-ES5 app is trying to access the port for your ES5. Usually this is a webspider or something, and it happens more often if you are using port 80 or port 443.


When a message arrives at the ES5, the first thing that is read is the length of the message. If it is too large, ES5 doesn't process the rest of the message, so there is very little CPU wasted. You still have bandwidth wasted of course.

When your own users connect, do they have problems? This looks to me as if some non-ES5 client is hitting your port. Because the message is nonsense as far as ES5 is concerned, the part of the message that ES5 uses to tell the length of the message can often be parsed into a very large number. These messages are coming in on your port 9899, which is strange for a web spider, but possible.

If you are sure that your own clients are having no problems, I would suggest just adding the following line to your server/config/log4j.properties file, which will suppress the lines above from the log. You will have to restart ES5 for it to take effect:


log4j.logger.com.electrotank.electroserver5.protoc ol.IOErrorHandler=error

There should be no space in that line; if the forum software puts one in, remove it when you edit log4j.properties.
