make_connection: connect failed (socket #5, error)

[canditw]

This have been happening to me frequently, the server runs fine with players in and out like normal but once in ahwile I will get this error and players who are trying to login will get *Server Closed (1)*, and a simple restart will fix this. But what seems to be causing this error? It usually happens after a day or two while the server is running.
 

 Char-server 'ARO' has disconnected.
[status]: Attempting to connect to Char Server. Please wait.
[status]: Connecting to xxx.xxx.xxx:6121
[Error]: make_connection: connect failed (socket #6, error 111: Connection refused)!
 
Somehow the char server crashed midway and goes into an endless loop of reconnection.

Update:
tried to check with a gdb core dump.

Got this error from the core file via gdb

And it goes on about the same thing getting about 10,000+ worth of this error or maybe even more. It just goes on forever.

any clues on this?
