Issue regarding reconnection. Eclipse Vortex in Discord pointed out that he was randomly having validators freeze up. Total freeze. He narrowed this down to this call in bittensor.core.extrinsics.utils:

response = substrate.submit_extrinsic(
    extrinsic,
    wait_for_inclusion=wait_for_inclusion,
    wait_for_finalization=wait_for_finalization,
)

Running v8.3.1, with wait_for_inclusion=True

I believe what is happening is that a subscription handler is created due to submitting the extrinsic with wait_for_inclusion=True, and then there is a connection interrupt. We are reconnecting, but due to how websockets work, our websocket connection will never receive the result of the subscription indicating success/failure. Thus, it is stuck in an infinite loop of polling.
