Done Server lag last few hours

There was been unbearable server lag over the last couple of hours. The TPS says it's fine, but the server lag is crazy. Nobody is sure what the cause is. Can we get some mod help to try to figure out the cause?

/edit this is ProjectOzone normal, not Titan

 

Was trying to troubleshoot with xxxdruidsrulexxx, but I didn't see anything obviously weird he had done. It got to the point where there were only a couple of us left on the server and it was still lagging. He was convinced it was him. I couldn't even teleport home from his chunks, the server would never complete the teleport command after 5 seconds.

 

Once xXdruidsrulexX and LLitaTroll (who was stuck at his base) left the server and it processed the next tick the server went back to normal.

 

I flew away from his base on next attempt. It lagged the server as soon as I logged in, and fixed when his chunks unloaded. He says he has no idea what could be causing it.

 

Are there any enderIO farm stations there? I heard that those cause a lot of lag.

 

Can we please get some mod help with xxdruidsrulexx base? He logged in again today and the server immediately tanked. We can't figure out what is going on there.

 

Sorry everyone, and SirWill, i did not know ender batteries would cause lag, im going to now be using tesseracts. Thanks Will!

 

Thanks SirWill!
