Dont have sufficient space in ThreadPool and cause that Threads stops unwantedly.

How to prevent it happens?

The threads of execution of a microprocessor can not be adjusted, for this, better buy a new machine or do not run the client on the same machine where the server is running publicly (This is a huge mistake). This to begin with.

If your server worked perfectly and today you have realized that log you were showing, then it is because some component of your system (RAM, hard disk or even the same processor) could be failing. Normally is the RAM memory. Use a ubuntu live CD to check the status of hard disks and/or RAM.

Check also the ram asigned to gameserver. You need at least 3072Mb + 3072Gb free (if you use geodata).

I do not think you have to go crazy

with the settings of the threads in the configuration of the server as I have seen in some forums, leave those settings as they come by default and ignore those stupid things.

Good luck!
