help provider: net.minecraft.world.WorldProviderSurface

Hello, I'm having a problem with my modded server
he sometimes disconnected from nothing
starts with a lock of about 10 seconds and causes disconnected soon after
and I get this error back

I do not know if this is in the correct area.
I'm new to the forum
and sorry my english
I'm using google translator
