Under normal network conditions and with low cluster load, Spark encounters AssociationError reported by Akka

[run597]

Version Information
Version release 2.2
akka-remote and akka-actor

Describe the bug
When using Spark, I encountered two errors related to Akka (version 2.2): 1) In the Spark driver logs, it indicates an AssociationError. 2) In the executor logs, it mentions Driver Disassociated. The cluster's network is functioning normally, yet these issues occur periodically and restarting Spark resolves them temporarily. I'd like to inquire about possible scenarios that could lead to these two errors.
