It's so annoying that the player drops the line and the log exceeds 10GB!

This error caused a large number of players to drop the line, or all of them. Error reporting can last a few minutes, or a dozen minutes, or more.
Someone has reported this problem before, is it not fixed well? If it doesn’t work, I’ll try to shut it down. I don’t want to waste time.

Repeat this error without warning, and don’t let me send any MOD lists that are completely pointless.

I can’t get any useful clues from him.

Can you try uploading your log to ?

Log more than 1 G, I cannot upload.

In that case, could you upload your log to mediafire?

So last time I saw this issue, it was cause by the person’s server getting overloaded and an optimization software killing all the connections to try to prevent DDOSing and such. I have also heard of it being cause by antivirus, and by a poorly implemented internal network switching system (at a hosting company).

You might want to monitor your CPU/RAM usage, and the running tasks, and see if its an outside task killing the connections first.

As Aaron1011 said, a log would probably be very helpful.

Damn, this is actually very bad.
