Well, I have a big problem. I have a server with rathena with many modifications and harmony system. It's been an online time and hadn't had any problem. The problem started two weeks ago.
The problem is that the server is stopped practically, without any specific action or time pattern. When this happens the following events happen:
-Doesn't show any error or warning in the emulator.
-According to the control panel the map, login and char server are ok.
-Users who were inside they freeze and when they come out and try to log-in again, they look this message "server still recognizes your last log-in".
-Users attempting to enter and weren't inside the time of the fall, can enter to the char-selection and when they choose one of them the server show "connection failed" message. In this case the message that throws the emulator is as follows:
That happen for no apparent reason and there is a pattern. It may take 3 days when it doesn't happen anything, and there are days that it happen until 5 times.
So far the only solution that I found is to restart the emulator and everything returns to normal, but as you know is the worst solution xD.
Due to the lack of error or any indication, I have no idea where to find the problem, I had never seen anything like that. So far all I can think of that explains the lack of any pattern is some kind of attack to the server or disconnect ports.
I need urgent help, any suggestion or idea would help.
