Thank you for reply.

I tried increase timeout-time to 120s,but Minecraft crashed again.
Thank you try my world.But My world don't works in my enviroment.

Yes you can increase it.
That is the time your server will lag before crashing.
The spawn area of your world works fine for me.

Thank you for reply and downloading my world data.

My spigot.yml timeout-time is default setting(60s).
Should I increase timeoute-time?(For example 120s)

And I will try dellete entities.

Please let me know when you find out about it in my world data.

I'm downloading the world now, but basically you have a glitchy entity (horse) in your world.
There isn't anything we can do with this.
I dont know if I will be able to find it, but your options are basically increase timeout time in spigot.yml and just wait it out, or to delete all entities.

Thank you for reply.
