Hello. I have a problem. When someone is connecting to server, console shows "Can't keep up! Did the system time change, or is the server overloaded?" error and server is lagging for 1-10 seconds, but often server crashes after it with "Read Timed Out" error. Examples of error logs: http://pastebin.com/73LAzgah Player connected to server and then "Read Timed Out" errors. http://pastebin.com/LQUqgCUe Other log. Plugins list: Thanks. UPD: Computer characteristics: Intel Core i7-2700k, 16GB RAM (8GB for server).
