Mindcrack V.7 Wireless Redstone Crash

[entourian]

The following error was caused with the nether suddenly spiking in tps and crashing the server. I need assistance because our server crashes at least daily due to this.

By the looks the nether got unloaded (everyone was on the "world") did you make something with wireless redstone in the nether?

 

[entourian]

Yah we have a mob grinder that has a wireless redstone on/off switch. Why? Is that a problem?

 

[Nessiroj]

Shouldn't be, but it seems to be. Try adding a chunkloader to the chunk where the mobgrinder is to see if it makes a difference.

your errorlog indicates a problem with WRE and the server crashes when the chunk gets unloaded.
