When this happend server maybe stuck making all npcs stop repply , and log to game not posible.

*Happend mostly when server are long time runing.

*Sometimes server not stuck even geting the error.

*Only get this error on server machine. never get it on  many Test computers

 

We a little confused about this error, dont know exactly the cause hope someone can tell me more about

 

thanks in advance
