Expected behavior

The node is running normally and no exception should be thrown.

Actual behavior

I deployed a node online and found an exception while checking the logs. I want to know what the specific error is, whether it has any impact on the system, and whether it will affect block synchronization or data consistency?

Frequency

Only appeared once.
