Start by reproducing the reported shutdown sequence with the Java pubsub example and the shown Kubo daemon command. Read the reported cmd/ipfs/daemon.go:590 stack trace and determine whether the failure belongs to this client or the daemon; done means the component and a reliable reproduction are identified.
