Random Zone Server Crash

[WumelorWrath]

Ok here is the problem. Just at random times, zone servers of mine will shut themselves down. I am running 10 zone servers and after like 2 hours only 2 are running. At the end of each of the server dos windows. It says this.

Automatic shutdown
Message:----SERVER SHUTDOWN----
Zone shutdown: going to sleep

I dunno what my problem could be. I am running it through my router, but i had this problem before i had it going through my router so i know its not that. Ill post my boot10zones.bat too

REM: ****Read this first!!!****

REM: This file requires your real IP in the place of "YourIP" when you are connecting
REM: To the EQEmu Loginserver.

REM: When you are using minilogin, Replace all IP Addresses to say 127.0.0.1

REM: If you still get errors try using localhost instead of 127.0.0.1
