Expected behavior

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

Actual behavior

An SR is deployed and only connected to fullnode A. After fullnode A is started, it had been synchronizing blocks normally for a while, but later it threw an exception. Does it have any impact on the system，and whether it will affect block synchronization?

Frequency

Only appeared once.
