NET ERROR Flooding my Error Logs

[trevius]

Starting yesterday, I noticed that I was getting a HUGE error log in one of the files called eqemu_debug_zone_xxxx.log and logged into the game and used the #iplookup and found it was a player from china that was causing the error. It was his first day playing on my server. This caused 100MBs of logs within a few hours. I edited my router settings to narrow down allowed ports and thought it would stop the error from hitting the server. I told the guy he needed to figure out what was causing it, or I would have to block him completely from my server. So, he logged off kindly, and I continued to get the error from his IP. Finally I rebooted the server with the new router settings in and it was back to normal. I deleted the log file, but made note of his IP for future reference if needed.

Today, I check my log files and now that file is up to 250MBs! This time it is coming from a player that has played on my server for a few days and I have never seen the error from him before now. He was on at the same time yesterday when the other log issue was happening, but it wasn't from his IP.

So, this is the error I am getting:

[02.07. - 23:42:29] [NET__ERROR] 24.167.163.206:1619: Tried to write a packet beyond the end of the queue! (40899 is past next out 40898)
[02.07. - 23:42:29] [NET__ERROR] 24.167.163.206:1832: Tried to write a packet beyond the end of the queue! (40815 is past next out 40814)
[02.07. - 23:42:29] [NET__ERROR] 24.167.163.206:2382: Tried to write a packet beyond the end of the queue! (40223 is past next out 40222)

It is those 3 lines about 50 times per second each!

Does anyone have a clue what that is? Is it dangerous, or can I ignore it? And if I can ignore it, can you please tell me exactly what I need to do to turn it off? I wish there was an easy way to turn off and on these debugs, but as far as I can tell, there is not. I don't need a debug to run unless I see a problem! Waste of system resources, IMO. There are too many debugs with too much information that is hard to read and even harder to understand.

If anyone has seen this error and knows what it means, I would like to know. Google came up with nothing from searching it.
