NullReferenceException in NetworkIdentity.RebuildObservers

I am running dedicated host on my small game.

After applying NetworkProximityChecker,
Sometimes NullReferenceException occurs, and once it occurs, every frame occurs.

Is this related to using object pools?
Is there a way to safely initialize NetworkIdentity for reuse?

Please help me.


This is Exception text :
-------------------------------

NullReferenceException: Object reference not set to an instance of an object
at UnityEngine.Networking.NetworkIdentity.RebuildObservers (Boolean initialize) [0x00000] in <filename unknown>:0
